Question #303599

The position of a stone dropped from a cliff is described approximately by x = 5t^2 , where x is in meters and t is in seconds. The +x direction is downwards and the origin is at the top of the cliff. Find the velocity of the stone during its fall as a function of time t.

We know that gives

x=5t2x=5t^2

Now velocity

v=dxdtv=\frac{dx}{dt}

Put value

v=d(5t2)dt=10tm/secv=\frac{d(5t^2)}{dt}=10tm/sec
