When a ball is thrown in the air straight up, what is the velocity at the top of its flight?

9.8 m/s up

0 m/s

9.8 m/s down

20 questions from our bank of first semester material

1 / 20

If a ball is thrown with a 7 m/s X component of velocity, what is the magnitude of X component velocity if still in the air after 1.3 seconds?

0 m/s

10 m/s

7 m/s

17 m/s

In projectile motion only the Y component of velocity is accelerated. The X component is in constant motion. If it was 7 m/s at the beginning it is still 7 m/s anywhere in the air unchanged.

2 / 20

What angle would you throw a ball to get the greatest Y axis distance?

25° to the horizontal

45° to the horizontal

65° to the horizontal

90° to the horizontal

The greater the angle to the horizontal the further up but less downrange. Directly up or 90° would get you the greatest height (Y axis distance)

3 / 20

A ball is thrown horizontally at 20 meters per second and takes 1.3 second to hit the ground. What happens to the time the object takes to fall if thrown much faster at 45 m/s?

It would take more than 1.3 seconds to hit the ground

It would take less than 1.3 seconds to hit the ground

It would take 1.3 seconds to hit the ground

The X and Y motion are independent. No matter how fast forward something is thrown, in the Y axis the object acts like it's falling. On earth an object falling from the same height would take the same time to hit the ground no matter how fast forward it is thrown or if it is just dropped. (ignoring air resistance)

If a car has a mass of 750 kg, how much force is required to stop the car if it was traveling 12.5 m/s and took 10 m to stop?

2434 N

5859 N

12230 N

1460 N

6 / 20

Sergio pushed a box with 50 Newtons of force forward. When it did not move he pushed the box even harder with 100 Newtons of force but the box still did not move. When did Sergio do more work?

When he pushed with a force of 50 N

When he pushed with a force of 100 N

Neither

W = Fd

If you do not move the object, you have done no work no matter how much force you apply

7 / 20

What will happen to the centripetal force required to keep an object going in a circle if mass, radius, and velocity are all doubled?

It would become ___________ times the original.

half

one

two

four

8 / 20

How would a ball travel if you were spinning a ball on a rope above your head and the rope broke?

directly outward from the center of the circle

directly forward tangent to the circle

inwards to the center of the circle

in and outwards repeditively

The ball will keep on going straight when there is not a centripetal force pulling it in. Straight from the outside of the circle is called tangent. So it would go straight ahead tangent to the circle.

9 / 20

How is the force of gravity related to mass?

directly

inversely

inversely squared

10 / 20

What is the spring constant of a spring displaced 0.1 meters when 400 N of force is applied?

40 N/m

4000 N/m

384 N/m

10 N/m

11 / 20

What is the tension in each of two ropes vertically suspending a 45 kg object? (use g = 9.8 m/s/s)

45 kg

441 N

0.218 N

221 N

Tension if a single rope would have the equal magnitude to the weight down. With two ropes both directed up, they are sharing the weight so divide by two.

F_w = mg

F_w = (45)(9.8) = 441 N

441/2 = 220.5 N

12 / 20

What is net force of a 1400 N skydiver at terminal velocity?

0 N

1400 N up

1400 N down

At terminal velocity a person is no longer accelerating so net force is zero because air resistance force is equal to the weight force

13 / 20

Net force causes _____________________. Pick the best answer

motion in the same direction

acceleration in the same direction

motion in the opposite direction

acceleration in the opposite direction

Net force causes an object to accelerate... not just move. Acceleration always occurs in the same direction as net force. If you are pushing something to the right with a greater force than friction, and its net force is to the right, it will accelerate to the right.

14 / 20

Which changes depending on your location?

mass

weight

Mass (kg) never changes because it is a measure of the matter that you are composed of. You are the same matter on earth or on the moon.

Weight (F_w) changes when g changes. g changes depending on your altitude on earth, in space, or on another planet (it is not always 9.8 m/s²which is why many classes use a more rounded 10 m/s²instead.

(F_w = mg)

15 / 20

What happens to the normal force as the angle of incline increases?

Increases

Decreases

Larger incline means less force into the hill (equal to the magnitude of normal force) as more of the weight is going into the component downhill instead

16 / 20

Which letter above represents normal force?

17 / 20

What is the acceleration of this object over the 30 second time period?

0.2 m/s/s

0.4 m/s/s

2.5 m/s/s

360 m/s/s

Slope of a velocity time graph is acceleration. Either find the slope or turn it into an equations picking givens off the graph (either way you are doing the same thing)

18 / 20

Which variable is bold in the following question:

How fast was Sam traveling if he is traveling at 16 m/s after accelerating at 2 m/s² for 25 meters?

A) v_i

B) v_f

C) a

D) t

E) x

F) v

the unit is (m/s) so its a velocity but there is acceleration so it is not just v

he is traveling at 16 m/s after accelerating at 2 m/s² so we know the final and the question asks for the initial

v_i = ?

19 / 20

What is your displacement after going 10 meters east followed by 3 meter west?

13 meters east

13 meters

7 meters east

7 meters west

7 meters

Displacement is a vector that includes direction. Make the direction a sign (east positive and west negative) before you add (10 + (-3)) = -7 meters which becomes 7 meters west

20 / 20

What is your distance after going 10 meters east followed by 3 meter west?

13 meters east

13 meters

7 meters east

7 meters west

7 meters

Distance is a scalar that has no direction. You do nothing with the direction and just add all the individual magnitudes up (10 + 3) here.

You can't put a direction on the final answer since it is a measure of how far you went totally and not a direction.

You should not put a direction on the final answer either since this is not a measure of where you are located but just how far you went in any direction.
