Question

A body of mass 100kg is accelerated uniform from a velocity of 5m/s to 10 m/s.Calculate the initial momentum of the body, final momentum of the body.Also find the force acting on the body per second

Answer 1

m=100kg
v=10m/s
u=5m/s

p=mu
p=100×5
p=500kgm/s

p=mv
p=100×10
p=1000kgm/s

f=ma
f=100(v-u)÷t
f=100(10-5)
f=500N
