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

$\huge\fbox\purple{Answer}$

1) Initial momentum = mass ✖ initial velocity

mass = 100

initial velocity = 5

100 ✖ 5

$500 \: kg \: m \: s {}^{ - 1}$

2) Final momentum = mass ✖ final velocity

mass = 100

final velocity = 8

100 ✖ 8

$800 \: kg \: m \: s {}^{ - 1}$

3)

$force \: = \frac{change \: in \: momentum}{time \: taken} \\ \\ \frac{800 - 500}{6} \\ \\ \frac{300}{6}$
