Kinetic energy is the energy possessed by a body by virtue of its motion. Before a body can possess such energy, it has to move away from its position of rest to another position. It has to move at a certain velocity.
ThIs is the same type of problem find out the time value 3 = 1/2*a*T^2 6/10 = t^2 t = 0.77 seconds and the distance is given 5 m thus speed ,= distance/time speed = 5/0.77 = 6.45 m/s
