.hockey ball of mass 200 gram travelling at 10 install buyhatke ST casset

Mass
of the hockey ball, m
= 200 g = 0.2 kg

Hockey
ball travels with velocity, v1
= 10 m/s

Initial
momentum = mv1

Hockey
ball travels in the opposite direction with velocity, v2
= −5 m/s

Final
momentum = mv2

Change
in momentum = mv1
− mv2
= 0.2 [10 − (−5)] = 0.2 (15) = 3 kg m s−1

Hence,
the change in momentum of the hockey ball is 3 kg m s−1.

Hope i helped

Because they're in different places for this the temperature varies.
