What type of collision is the following?

A 0.25 kg ball of clay is thrown at 6 m/s towards a 0.8 kg toy car at rest. How fast is the clay stuck to the car traveling after the collision?

elastic collision

inelastic collision

neither

In an elastic collision objects maintain their shape and travel independently afterwards

In an inelastic collision at least one object changes its shape and heat is lost

0.62 m/s left

4.1 m/s left

3.2 m.s right

5 / 10

How does padding make it safer for athletes on impact?

it decreases the change in momentum decreasing the force

it decreases the impulse decreasing the force

it increases the time of impact decreasing the force

It does not decrease the momentum since it does not decrease the mass, staring, or ending velocity. This is equal to impulse and therefore does not decrease that. It increases the time the force is applied for and thus decreases the force.

6 / 10

How many times does impulse change when you double the force applied?

1/2 times

2 times

1/4 times

4 times

7 / 10

What is the change in momentum of an 85 kg person running at 8 m/s forward when hitting a wall and bouncing back at 3 m/s?

-935 kg∙m/s

435 kg∙m/s

-1251 kg∙m/s

894 kg∙m/s

8 / 10

How much more momentum would a moving object have with twice the mass?

1/2 times

2 times

4 times

1/2

9 / 10

Which would change the momentum of an object the most.

double force and double time it is applies

triple force and decrease the time applied by a half

double force and keep time applied the same

one third the force applied for half the time

Impulse changes the momentum and the equation is J = Ft

Both force and time applied are directly related to impulse. Doubling both would create four times the impulse and would be the greatest of the choices.

10 / 10

Impulse is equal to

change in momentum

force times time

mass times change in velocity

all choices

The main impulse equation if J=Ft
Impulse is also equal to change in momentum
Change in momentum is equal to mass times change in velocity

What type of collision do you have when both momentum and kinetic energy are conserved?

elastic collision

inelastic collision

neither both momentum and kinetic energy are never conserved

In an elastic collision momentum and kinetic energy are conserved

In an inelastic collision momentum is conserved but kinetic energy is not

Kinetic energy is only a part of the entire energy. The entire energy would be conserved in either case but the definition is only talking about kinetic energy.

elastic collision

inelastic collision
