Question

A body of mass 25kg has a momentum of 10 kg m/s. Find its Kinetic energy

Answer 1

A body of mass 25 kg has a momentum of 125 kg m/s . Calculate the velocity of body

Top answer · 7 votes

Mass of the body,m = 25 kgMomentum p = 125 kg.m/s p = m × v Mass of the body, m = 25 kg Momentum p = 125 kg.m/s , p = m × v v = pm = 12525 = 5 m/s Velocity .

Answer 2

Answer:

Mass of the body,m=25 kg

Momentum p=125 kg.m/s

p=m×v

Mass of the body, m=25kg

Momentum p=125kg.m/s,

p=m×v

v=

m

p

=

25

125

=5m/s

Velocity of the body is 5 m/s
