An object of mass 100 kg is accelerated uniformly from a velocity of 5 m s -1 to 8 m s -1 in 6 s. Calculate the initial and final momentum of the object. Also find the magnitude of the force exerted on the object.

Question

Philoid · Accepted Answer

Firstly, we have to calculate the initial momentum:

= Mass × Initial velocity

= 100 × 5

= 500 kg m/s (i)

Now, we will find the final momentum

= Mass × Final velocity

= 100 × 8

= 800 kg m/s (ii)

Now,

Force =

=

= 50 N

An object of mass 100 kg is accelerated uniformly from a velocity of 5 m s-1 to 8 m s-1 in 6 s. Calculate the initial and final momentum of the object. Also find the magnitude of the force exerted on the object.
