Question

a body weighing 5 kg moves with a velocity of 10m/s and stops after 2s. find the initial and final momentum of the body​

Answer 1

Answer:

Initial Momentum=50 kg m/s;Final Momentum=0 kg m/s

Explanation:

Initial Momentum=mass* initial velocity

                            =5*10=50 kg m/s

Final Momentum=mass*final velocity

                           =5*0 (Object has stopped so final velocity is 0)

                           =0 kg m/s

Answer 2

Answer:

Mass=5 kg

Initial Velocity=10m/s

Final Velocity=0 m/s

Time=2 sec

Explanation:

Initial momentum,p=m×u

p=5×10

p=50 kg m/s

Final momentum,p=m×v

p=5×0

p=0 kg m/s

Answer:- Initial momentum = 50 kg m/s

Final momentum = 0 kg m/s
