Answer: cricket ball have higher
Momentum
Explanation: given
Bullet mass= 10kg Cricket ball mass=400g=0.4kg
Velocity of the bullet=400m Velocity of the cricket ball=90km=90000m
We know
Moment= mass×velocity Moment of the bullet = 10×400
=4000kg.m/s
Again
Moment of the cricket ball=0.4×90000
=36000kg.m/s
Therefore the cricket ball have higher moment is = 36000kg.m/s
