Answer»

Answer:

We know force F=mass×acceleration-------(1)

Given time = 2 seconds

We can rewrite the EQUATION (1) as

Force=mass×

Time(t)

Final(v)-Initial VELOCITY(u)

--------(2)

Also change in momentum dp=p

final

−p

initial

= mass×change in velocity

Equation (2) becomes F=

Fdt=dp

Integrating the above equation we get:

F∫

dt=∫

30×2 = P

−P

Therefore change in momentum = 60 kg m/s
