Select the best equation that would help solve the problem: Ball A and Ball B have the same mass. Ball A rolls and collides with Ball B at rest. Ball A rolls with some velocity after the collision, what is the velocity of Ball B ?

(before) m A v A + m B v B = m A v A + m B v B (after)

(before) m A v A + m B v B = (m A + m B )v (after)

Select the best equation that would help solve the problem: An arrow collides and sticks with a target that is hanging on a string with negligible mass. To find the velocity of the arrow and target after the collision.

(before) m A v A + m B v B = (m A + m B )v (after)

(before) m A v A + m B v B = m A v A + m B v B (after)

The canon ball has a mass of m and the cannon has a mass of 100m . After the canon ball is fired from the canon, the greater acceleration is experienced by...

the canon ball due to its very low mass

the canon due to its very low size

the canon due to its very large size

the canon ball due to its very high mass

When gymnasts vault over the horse and land, they land on a big pad. How does the pad help them?

It increases the time it takes to stop, so the force is less when they land.

It reduces the amount of momentum they have when they land

It reduces the change of momentum when they land.

It reduces the total impulse when they land.

It reduces their inertia when they land.
