Question

An object of mass 100kg is accelerated uniformly from a velocity of 4 m/s to 8 m/s in 2 seconds. Calculate the initial and final momentum of the object a. 400 kg m/s,800 kg m./s b. 100 kg m/s,400 kg m./s c. 200 kg m/s,400 kg m./s d. 400 kg m/s,400 kg m./s

Answer 1

Explanation:

this may help you

I hope u will solve the question

Answer 2

initial momentum = mass × initial velocity

= 100 × 4

= 400kg m/s

final momentum = mass × final velocity

= 100 × 8

= 800kg m/s
