Question

an object of mass 100 kg is accelerated uniformly from a velocity of 5 MS power to the - 1 to 5MS power to the - 1 in 16 seconds . Calculate the initial and final momentum of the object . Also, find the magnitude of the force exerted on the object.

Answer 2

☺ Hello mate__ ❤

◾◾here is your answer...

u = 5 m/s

v = 8 m/s

m = 100 kg

t = 6 s

Initial momentum = mu = 100 × 5 = 500 kg ms-1 Final momentum = mv= 100 × 8 = 800 kg ms-1

Force exerted on the object,

= (mv−mu)/ t

= 800 - 600 / 6

= 300 / 6

= 50 N

Hence, Force exerted on the object is 50 N.

I hope, this will help you.

Thank you______❤
