What if the acceleration is not constant? A particle starts from the origin with velocity m/s at t= 0 and moves in the xy plane with a varying acceleration given by a= (6t j) m /s2 , where t is in s. (a) Determine the vector velocity of the particle as a function of time. (b) Determine the position of the particle as a function of time.
