The displacement of an object is "s" is given as a function of the time "t" .
If; "s"=5t2+9t, calculate the instantaneous velocity of object at "t"=0.
The displacement (in meter) of a particle moving along the x-axis is given x=18t+5t2. Calculate
(A) The instantaneous velocity at t = 2 sec
(B) Average velocity between t = 2 sec and t = 3 sec
