Question

A particle moves along the x-axis so that its velocity at time t is given by v(t)= (t^6-13t^4+12)/(10t^3+3). At time t=0, the initial position of the particle is x=7.

(a) Find the acceleration of the particle at time t = 5.1

(b) Find all values of t in the interval 0 ≤ t ≤ 2 for which the speed of the particle is 1

(c) Find the position of the particle at time t = 4. Is the particle moving toward the origin or away from the

origin at time t = 4 ? Justify your answer.

(d) During the time interval 0 < t ≤ 4, does the particle return to its initial position? Give a reason for your answer
