(2) in r', a point mass m, moves with the velocity vi(t) = (1, tcost, tsint) and the original position r(0) = (-1,1,0). another point mass m, has the position function ra(t) = (t? , 2 cost, 2 sint). (a) compute ri(t), the position function of m. (b) denote l1 (8) and la(s) be the distance traveled by m, and m, from t = 0 tot 8 respectively. find l2 (2019)/l (2019).
