Hii guys ...!!! One more question.....
An object of mass 100 kg is accelerated uniformly from a velocity of 5 ms^-1 to 8 ms^-1 in
6 s. Calculate the initial and final momentum of the object . Also, find the magnitude of the force exerted on the object.
plz ....meaningful answer....

u = 5 m/s
v= 8 m/s
t=6s
v= u + at
8 =5 + a ( 6)
a =3/6=0.5 m/s^2
initial momentum =mu =100 * 5=500kg m/s
final momentum =mv =8*100=800kg m/s
F =ma
100 *0.550 (N
