Question

an object of mass 1000 kg is accelerated uniform from a velocity of 5 M per second to 8 M per second in 6 seconds calculate the initial and final momentum of the object also find the magnitude of the force exerted on the object

Answer 1

Inital momentum = mv1 =1000 ×5 = 5000
Final momentum = mv2 =1000×8 = 8000
Force = change in momentum /time
= 3000/6 =500 N

Answer 2
