Net force acting on particle of mass 2 kg is 10N in north direction.At t=o, particle was moving eastwards with 10m/s. Find displacement and velocity of particle after 2 seconds.
Solution) given force =F=10N
mass M=2kg
velocity u=10m/s
then acceleration a=F/M=10/2=5m/s^2
then displacement=s=ut+1/2at^2
here u=initial velocity
t=time
a=acceleration
then we get the displacement is=30m
2.velocity=u+at
then we get velocity as 20m/s.
