The change in momentum is -350 kgm/s

Momentum is the product of the mass of a body and its velocity. It is a vector quantity and is measured in kgm/s.

During a collision there is a change in momentum. The force produced as a result of the collision is equal to the rate of change of momentum.

The change in momentum is the product of mass and change in velocity.

Change in momentum = mass * change in velocity

Change in momentum = 70kg * (5m/s - 10m/s) =

Change in momentum = -350 kgm/s

Therefore the Change in momentum is 350 kgm/s in the opposite direction.
