6. Two particles leave the origin at the same time and move along the y-axis with their respective positions determined by the functions y1 = cos 2t and y2 = 4sin t for 0 < t < 6. For how many values of t do the particles have the same acceleration?

7. Find the distance traveled (to three decimal places) in the first four seconds, for a particle whose velocity is given by v(t) = 7e-t2, where t stands for time.
