(7 points): The upward normal force exerted by the floor is 620 N on an elevator passenger who weighs 650 N. Is the passenger accelerating? If so, what are the magnitude and direction of the acceleration? (Take g = 9.8 m/sz) Problem 2. (8 points): The position of a 2.75 x 10'N training helicopter under test is given by T = (0.020 33) 131 + (2.2 m/s)tj - (0.060 -2) t2 F. Find the net force on the helicopter at t = 5.0 s. (Take g = 9.8 m/s2)
