Question

If a curve is drawn expressing the K.E. of a particle as a function of the distance on x-axis.   The slope of this curve represents the instantaneous 

Moderate
Solution

Conceptual    W   =    F.S

Slope : Workdisplacement   =   Force---(1) from work energy theorem , work done =change in KE---(2) substitute eqn (2) in (1) KEdisplacement=Force=slope of the curve k.Es=mv22s=ma=Force acceleration =v22s
