Question

An object of mass100kg is accelerated uniformly from a velocity of 5m/s to 8m/s in 6s. Calculate the initial and final momentum of the object. Also find the magnitude of the force exerted on the object.

Answer 1

Momentum, p = mv
Initial momentum = 100 × 5 = 500 kg ms^-1
Final momentum = 100 × 8 = 800 kg ms^-1
acceleration = v-u/t
= 8-5/6 = 1/2 = 0.5 ms^-2
Force = ma = 100 × 0.5 = 50 N

HELLO FRIEND HERE IS YOUR ANSWER,,,,,,,,


ANSWER :

Refer and consult to the following attachments for a detailed explanation and step by step solution with vital elaborations for certain formulas used into this query to arrive at a final conclusion that is,,,,


$\boxed{\bf{Initial \: Momentum = 500 \: Kg \: m/s}}$


$\boxed{\bf{Final \: Momentum = 800 \: Kg \: m/s}}$


$\boxed{\bf{Force = 50 \: N}}$


HOPE IT HELPS YOU AND CLEARS THE DOUBTS TO FIND THE INITAL AND FINAL MOMENTUMS AND FORCE EXERTED ON THE GIVEN OBJECT!!!!!!!
