Problem
Two identical balls P and Q each of mass m move along the same straight line.
• Ball P slows down from 10m/s to 6m/s.
• Ball Q is initially at rest and then speeds up to 4m/s.
Ignoring all external influences, which statement is correct about the magnitudes of impulse imparted to the two balls?
(a) Impulse on P is greater than on Q
(b) Both balls receive equal impulse
(c) Impulse on Q is greater than on P
(d) Comparison cannot be made without knowing m
