Question

calculate the initial and final momentum of the object t. also , find the magnitude of the forceexerted on the object?

Answer 1

Let the mass of object is m

and velocity at time=0 is U

velocity at time=n is V

Momentum (p)=mass (m) ×Velocity

intial Momentum =mU

final momentum =mV

Avg momentum =m (V-U)

Force=p/time

Force=(mV-mU)/time
