A 120-kg block slides towards a stationary 55-kg block at a speed of 6 m/s. What is the maximum possible loss of kinetic energy (in joules) for this collision? Round to the nearest integer.

Hint: What kind of collision leads to the greatest loss of kinetic energy? Use conservation of momentum to find the velocities of each block after the collision.

Answer #1

Dear Student,

Maximum loss of kinetic energy will happen in case of fully non elastic collision.

In case of non elastic collision the two mass will be fused together and will move in a constant velocity.

But total momentum must be conserved before and after collision as follows...

A rubber block (m= 20.0g) slides along a frictionless table at v=2.00m/s directly towards a steel block (m= 0.0500kg), which is at rest on the table. After an inelastic collision, in which 25% of the system's kinetic energy is lost, the rubber block rebounds the way it came at a reduced speed. Determine the speed of each block after the collision.
