A massless string is attached to the I w mass, and run over a frictionless pulley to a hanging mass of B.O kg. If the hanging mass is released, what is the acceleration of the system? OD m/s Question 2 (1 point) The free-body diagram below represents a 2000-kg elevator. What is the motion of the elevator if the tension in the cable is 1.96 x10" IN? [Assume 3 significant digits.] The elevator might be accelerating upward. The elevator might be accelerating downward. The elevator must be accelerating. The elevator cannot be undergoing uniform motion. The elevator must not be accelerating. Question 3 (1 point) Consider two planets, A and B. Planet A has half the mass and half the radius of planet B. The ratio of RA : 1, would be Q2:1 Q1:2 04:1 Q1:4 1:1 Question 4 (1 painil A block of ice is sliding over a floor with a cocifident of kinetic friction of 0.228. If the block is moving at 4.24 m/'s, how long will it take to come to a stop? The block will not come to a stop. 0.433: 1.905 4.245 Question S (1 point) Two people pushing an object against friction across a surface will result in twice the acceleration than if only one person pushes. Assume that the object slides in both cases and that both people push with the same force. True False Question & (1 point!
