Collision Analysis Momentum

A block of mass m=8.5kg, moving on a frictionless surface with a speed vi=6.6m/s, makes a perfectly elastic collision with a block of mass M at rest. After the collision, the 8.5 block recoils with a speed of vf=0.5m/s. In the figure, the mass M is closest to:

• 9.1kg

• 7.1kg

• 8.5kg

• 120kg

• 9.9kg

A block of mass m=25kg has a speed V and is behind a block of mass M = 82kg that has a speed of 0.5m/s. The surface is frictionless. The blocks collide and couple. After the collision, the blocks have a common speed of 0.9m/s. In the figure, the loss of the kinetic energy of the blocks due to the collision is closest to:

• 7.7J

• 13J

• 28J

• 33J

• 94J

In the figure, determine the character of the collision. the masses of the blocks, and the velocities before and after are given. The collision is:

• characterized by an increase in kinetic energy

• perfectly elastic

• partially inelastic

• completely inelastic

• not possible because momentum is not conserved
