Question

the velocity of a particle of mass 150 gram changes from 8 metre per second to 12 metre per second into second I'm using that a constant force acts on it find the magnitude of the force

Answer 1

We know that force = dp/dt

mass=m=0.150 kg

del v=velocity change =4m/s

apply

p=m×del

p=0.150×4

p=0.600Ns

force =0.600/2N

force =0.3 N
