question_answer 16)

An object of mass 100 kg is accelerated uniformly from a velocity of 5 m s–1 to 8 m s–1 in 6 s. Calculate the initial and final momentum of the object. Also, find the magnitude of the force exerted on the object, 

Answer:

Here, m = 100 kg u = 5 m s-1                                                                Initial momentum of object, Final momentum of object, Force exerted,
