Question

a force of 10newton acts on a body of mass 20kg for 10sec the change in momentum is??​

Answer 1

Answer:

30 seconds in the Newton acts

Answer 2

Explanation:

given

Force = 10N

Mass= 20kg

since

F = ma

10kg = 20a

a = 0.5m/s^2

t = 20s

(final velocity - initial velocity )time = a*t = 0.5*20=10 m/s

change in momentum = m(final velocity - initial velocity)

= 20*10= 200kgm/s
