Question

A body weighing 5kg moves with a velocity of 10m/s to 50m/s. Calculate its change in momentum

Answer 1

Answer:

200 kgm/s

Explanation:

where , mass (m)=5kg

initial velocity(v1)=10 m/s

final velocity(v2)=50 m/s

change in momentum=m(v2-v1)

=5(50-10)

=5×40

change in momentum=200 kgm/s

Answer 2

Answer:

Explanation:

given,

mass = 5 kg

intial velocity = 10m/s  

final velocity = 50m/s

change in momentum = mv - mu

                                    =  5*50 - 5*10

                                    =  250 -50

                                    =  200 kg. m/s
