A4 Curves: Problem 13 (1 point) A child wanders slowly down a circular staircase from the top of a tower. With :13, y, z in feet and the origin at the base of the tower, her position if minutes from the start is given by m : 15cost, y : 15sint, z = 90 5t. (a) How tail is the tower? height = ft (b) When does the child reach the bottom? time = minutes (0) What is her speed at time 75? speed = ft/min (d) What is her acceleration at time t? acceleration = ft/min2
