Question

calculate the momentum of a bullet of mass 0.25kg moving in a straight line with a speed of 450km/hr. What will be
the momentum after collison with a rock
​

Answer 1

Explanation:

Momentum = mass × velocity

M = 0.25 × 450

M = 112.5 kgm/s

When two objects collide, their total momentum does not change. The total momentum, before and after the collision, equals the sum of the objects' individual momenta
