sir how can we use s=0.5at^2. it is used only when acceleration is constant. Here we cant say that as force can be changing with time so does acceleration

										Force has a constant value...                      So acceleration is also constant.....                       So we can use it in that case..............................

POWER = WORK DONE/ TIME = CHANGE IN KINETIC ENERGY PER TIME
              = ½*M*V2/T  =  ½*M* (S/T)2/T 
              = ½*M*S2/T3
S2=CONSTANT* T3
HENCE S IS PROPOTIONAL TO T3/2.
