Question

If a body of mass 3 kg are moving with initial velocity 5 metre per second on applying a force its final velocity becomes 25 metre per second calculate acceleration change in momentum and impulse​

Answer 1

Answer:

momentum = 60 N-s

impulse = 60

Explanation:

change in velocity = 25-5 = 20 m/s

momentum = mass *velocity

p = mv

p = 3*20 =60 N-s

a= change in velocity/change in time

change in time = change in velocity/a

change in time = 20/a

impulse = Fnet× change in time

impulse = 3*a*20/a

impulse = 60
