C. The arm of the robot is extending at a constant rate r dot-2 ft/s when r - 4 ft, z = (31²) ft, and 0 (t) = (0.5t) rad, where t is in seconds. What is the magnitude of the velocity of the grip A when t = 7 s. Give your answer with 2 decimals. d. Be careful, you have new numbers, you need to recalculate your values. The arm of the robot is extending at a constant rate r dot-0.5 ft/s when r=3 ft, z = (3t²) ft, and (t)- (0.8t) rad, where t is in seconds. What is the magnitude of the acceleration of the grip A when t = 6 s. Give your answer with 2 decimals.
