Question

An object of mass is 200kg accelerated from a velocity of 5m/s to 8m/s in 6 sec . calculate the intial and final momentum of the object ; also find the magnitude of the force exceted . ANSWER ME FASt

Answer 1

hello here is your answer

mass = 200kg.
initial velocity = 5m/s
final velocity= 8m/s
time= 6 seconds.

initial momentum= mu
= 200×5
= 1000kgm/s

final momentum = mv
= 200×8
= 1600kgm/s.

force = ma
so, a= v-u/t
= 8-5/6
= 1/2 = 0.5m/s^2

so, F=ma
F= 200×0.5
100N

hope it helps!!
