1. An elevator of mass M is pulled upwards at constant velocity by a cable. What is the tension in the cable (neglecting the mass of the cable)? A. less than zero C. equal to Mg B.between zero and Mg D.greater than Mg E.zero 2. Which force is directly responsible for your ability to walk? A. weight B. Friction C. Normal Force D. Force of Tension 3. A 65 kg woman is inside an elevator. Calculate her apparent weight (Normal Force) for the following cases: a. The elevator moves at constant speed of 10 m/s downward b. The elevator accelerates upward at a constant rate of 2.4 m/s' c. If the scale read 450 N. Find the magnitude and direction of the elevator's acceleration. 4. At the local hockey rink, a puck is given an initial speed of 4.4 m/'s as it slides down the hockey rink. (A) Draw a FBD of the sliding hockey puck (B) If the coefficient of kinetic friction between the ice and the puck is 0.11, what displacement does the puck slide before coming to rest
