Question

an object of mass 100 kg is accelerated uniformly from a velocity of 5m/s to 8n/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

mass of object = 100
initial velocity , u = 5m/s
final velocity , v = 8m/s
time , t = 6 s
initial momentum p1= mu
100×5= 500kgm/s
final velocity , p2 = mv
100× 8 = 800 kgm/s

so the magnitude of force
f= p2-p1/t
= 800-500/6
= 300/6
= 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!!!!!!!
