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
The position of a body moving along the x-axis at time t is given by t2−4t+6. The distance traveled by body in time interval t= 0 to t = 3 s is
