Question

calculate the force acting ona body which change the momentum of a body at the rate of 1 kg/ms2

Answer 1

Force = 1 N ,because change in momentum per second is called force and here rate is 1 kg- m/s^2 so force is also 1 N ,it's by 2nd law of motion.

i hope it will help you

Answer 2

rate of change of momentum equals force according to newton second law of motion
hence force equals 1
