Question

object of mass 100 kg is accelerated uniformly from a velocity of 5 metre per second to 8 M per second in 9 seconds find the initial and final momentum of the object also find the magnitude of force exerted on the object

Answer 1

Initial Momentum = m×u
=>500kgm/s
Final momentum = m×v
=> 800kgm/s
F= 100 × (8-5/9)
F=33.3N
