10 - 2D Motion Questions

1 / 10

What is the actual speed of a ball is thrown with an X component velocity of 7 m/s forward and a Y component of velocity of 30 m/s up when at the top of it's flight path?

30.1 m/s

10 m/s/s

35.2 m/s

7 m/s

At the top of a flight path the y component of velocity is 0 m/s temporarily so speed is only made up of the horizontal component. So 7 m/s here.

2 / 10

What is the actual speed of a ball is thrown with an X component velocity of 7 m/s forward and a Y component of velocity of 30 m/s up?

30.1 m/s

10 m/s/s

35.2 m/s

7 m/s

Actual speed would be the hypotenuse of the two vectors placed head to tail. You would do the Pythagorean Theorem.

The direction does not matter because it asks for speed which is a scalar.

3 / 10

What angle would you throw a ball to get the furthest X axis distance?

25° to the horizontal

45° to the horizontal

65° to the horizontal

90° to the horizontal

4 / 10

A vector includes

magnitude

direction

both magnitude and direction

A scalar has a magnitude only which includes a number and unit (15 meters)

A vector has a magnitude and a direction (15 meters north)

5 / 10

What is the direction of the resultant of 50 meters north and 72 meters west?

22 degrees south of west

66 degrees north of west

39 degrees west of north

55 degrees west of north

6 / 10

What is the magnitude of the resultant of 50 meters north and 72 meters west?

103 m

65 m

88 m

32 m

7 / 10

How would you describe the direction above?

35 degrees east of south

35 degrees south of north

35 degrees south of east

35 degrees north of west

The direction is 35 degrees in the south direction. The south direction is from the baseline east.

8 / 10

What is the minimum magnitude of vector A and B in any arrangement?

Magnitude includes the number and a unit. Since no numbers are involved the length of the arrow represents the magnitude. The directions are pointing the same way but the lengths are different.

Maximum is B + A or A + B

9 / 10

What is the correct description of this exact angle?

17 Degrees North of West

17 Degrees West of South

17 Degrees North of East

17 Degrees South of West

10 / 10

What is the maximum these two vectors can be when added together?

The maximum is when you put the two vectors in the same direction head to tail. Had to tail means the second starts where the last left off.

20 - 2D Motion Questions

1 / 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)
