X= (Simplify your answer. Use a comma to desperate answers as needed) Question # 2 . The displacement s (in cm) of a linkage joint of a robot is given by s = (7t - t^2)^2/3, where t is the time (in s). Find the velocity of the joint for t = 3.25 . Question # 3 .The lowest flying speed v(in lb/ft^2) at which a certain airplane can fly varies directly as the square root of the wing load w(in lb/ft^2). If v = 92 ft/s for w = 16 lb/ft^2 ,. find the derivative of v with respect to w . Question # 3 . Evaluate the second derivative of f(x) = ?x^2 + 11 for x = 5 .
