Acceleration is defined as the rate of change of velocity. Suppose we call the rate of change of acceleration as 'SLAP', (i) What is the unit of SLAP?(ii) How can we calculate instantaneous SLAP?

Answer:

                Since a stone thrown vertically up with speed u returns back the same point with the same speed, hence both the stones will strike the ground with the same speed. Hence the ratio of the speeds of the two stones will be 1:1.
