Question

An object of mass 100 kg is accelerated uniformly from a velocity of 5 ms to 8 ms in 6
seconds. Calculate the initial and final momentum of the object. Also find the magnitude of the
force exerted on the object.​

Answer 1

Explanation:

Final velocity = 8ms

initial velocity = 5ms

acceleration= v-u

Answer 2

Answer:

Initial velocity=m×v

100×5=500kgm/s

Final velocity=m×v

100×8=800kgm/s

Using first equation of motion.

v=u+at

8=5+a×6

3=6a

a=0.5m/s

Force=m×a

100×0.5=50N.
