A particle, initially at rest on a frictionless horizontal surface, is acted upon by a horizontal force which is constant in size and direction. A graph is plotted between the work done ( ) on the particle, against the speed of the particle, ( ). If there are no other horizontal forces acting on the particle the graph would look like a)b)c)d) |
