1. Two bowlers, a man and a women, are standing on either end of the same well oiled bowling
lane. The man throws a 16 ib (7.26 kg) ball down the middle of the alley at a velocity of 8.44
m/s. At the same time the women throws her 14 lb. ball down the middle of the alley at a
velocity of 8.67 m/s. The balls collide in an elastic collision. Answer the following questions.

15. Does this show conservation of momentum?
16. Does this show Conservation of Kinetic enery?
17. What was the force of impact of the two balls?

2. Solution
Question given is quite incomplete.
However , momentum and kinetic energy are conserved in the collision as the impact is elastic in
nature
