1. A particle of mas5s 1kgis moving along the x -axis. There is no force on the particle except during the time interval betweent=0s and t = 5s, when a force of the form F(0) = 12 N/s* acts on it. If the velocity of the particle at t = 0 is 50m/s, its velocity at t = 10s is:

    At the end of 5 sec, velocity of mass is 500 m per sec, as I have calculated below. Now there is no force after 5 sec, so whatever velocity the body has at 5th sec, the mass will carry on with that same particular velocity on 6th,7th,8th,... All sec, unless and untill any other accelerating or deceleration force acts on it. Thus, it's velocity at after 10 sec will also be 500 sec. Ask if any further doubt.
