Question

an object of mass 100 kg is acceleraled uniformly from a velocity of 5 M per second 8 M per second in 6 second calculate the initial and final momentum of the object also find the magnitude of face exerted

Answer 1

here
m= 100kg
v1= 5m/s
v2= 8m/s
t= 6 sec
so
initial momentum p1 = mv1 = 100×5 =500kg m/s
final momentum p2 = mv2= 100×8 = 800kg m/s
Also , the magnitude of force exerted is
F =(p2-p1)/t
= (800-500)/6
= 300/6
= 50N

Answer 2

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!!!!!!!
