Linear Momentum

A 3 kg object moving at 4 m/s collides inelastically with a stationary 1 kg object. After the collision, the 3 kg object is moving at 2 m/s in the same direction. How much kinetic energy is lost during the collision?

A 2 kg lump of clay moving at 3 m/s collides perfectly inelastically with a 1 kg lump of clay at rest. What fraction of the initial kinetic energy is lost in the collision?

Which of the following scenarios best represents an elastic collision?

In a perfectly inelastic collision, what is true of the objects after the collision?

In an elastic collision, what is conserved?

A 2 kg ball moving at 5 m/s collides elastically with a stationary 1 kg ball. After the collision, the 2 kg ball moves at 1 m/s in the same direction. What is the velocity of the 1 kg ball after the collision?

In an inelastic collision, what happens to the kinetic energy that is lost?

Two objects with masses $m_1$ and $m_2$ and initial velocities $v_{1i}$ and $v_{2i}$ respectively, undergo an elastic collision. Which equations must be solved simultaneously to find the final velocities $v_{1f}$ and $v_{2f}$?

A 5 kg object moving at 3 m/s to the right collides elastically with a 2 kg object moving at 2 m/s to the left. After the collision, what are the velocities of the two objects?

A ball is dropped from a height $h$ onto a hard floor and bounces elastically. After the first bounce, it reaches the same height $h$. If the collision were followed by projectile motion where the ball is launched horizontally, what additional information is needed to determine the range of the projectile?
