# AN OBJECT OF 100KG IS ACCELERATED UNIFORMLY FROM A VELOCITY OF 5M/S TO 8M/S IN 6SECOND .CALCULATE THE INITIAL AND FINAL MOMENTUM OF THE OBJECT.ALSO FIND THE MAGNITUDE OF FORCE ASSERTED ON THE OBJECT???

Final momentum=mass*final velocity=(100*8)=800 kg m/s

Force=Rate of change of momentum

Force=m(v-u)/t

=100(8-5)/6

=100*3/6=50 N

time taken = 6 sec.

initial velocity = 5 m/s.

final velocity = 8 m/s.

initial momentum of the object = 100*5=

final momentum of the object = 100*8=

force required = rate of change of momentum / time taken.

force=(800 - 500) / 6

force=300/6

force=
