Question

4. Two balls with masses of 1.70 kg and 5.60 kg travel toward each other at speeds of 13.0 m/s and 3.80 m/s, respectively. If the balls have a head-on inelastic collision and the 1.70-kilogram ball recoils with a speed of 7.60 m/s, how much kinetic energy is lost in the collision?

Step 1

From the conservation of momentum, the recoil velocity of the second ball is,

Step 2

The equation for the kinetic energy lost is,

Step 3

Substituting the...
