Problem
The position of a particle moving along the x-axis is given by x=3t2+2t metres, where t is the time in seconds. A constant force of 10N acts on the particle along the positive x-direction.
(i) Determine the velocity of the particle as a function of time.
(ii) Calculate the instantaneous power delivered by the force at t=4s.
