an object of mass 50 kg is accelerated from a velocity of 4 metre per second 8 metre per second in 8 second calculate the initial and final momentum of the object and also find the force exerted on the object. |

Answer» We are given that Mass of object (m) = 100 kg Initial velocity (u) = 5 m/s Final velocity (ν) = 8 m/s TIME = 6 sec. Initial momentum of the object = mu = 100 x 5 = 500 kg m/s ∴ Final momentum of the object = MV – 100 x 8 = 800 kg m/s ∴ Magnitude of the force exerted on the object (F) = Change in momentum T i m e Change in momentumTime = 800 − 500 6 = -object-of-mass-100-kg-is-accelerated-uniformly-from-a-velocity-of-5-m-s-to-8-m-s-in-6-sHope it helps you keep SMILING :) |
