A massless string is attached to the mass, and run over a frictionless pulley to a hanging mass of 8.0 kg. If the hanging mass is released, what is the acceleration of the system? Oom/s? ( 3.8 m/s2 O 6.0 m/s2 O 9.8 m/s2 Quiz Information 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* N? (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. O 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 BA : 8p would be 2:1 O 1:2 04:1 1:4 01:1 Question 4 (1 point) A block of ice is sliding over a floor with a coefficient 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. O 0.433 s 1.90 s O 4.24 s Question 5 (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.

According to Newton's Third Law, the 20 kg rock will experience an acceleration of 04 m/s LEI Q a m/s [EI O4 m/s [w] Question 3 (1 point) > Sad A mass of 12.0 kg is placed on a table. A string is tied to the mass, and run over a pulley to a hanging mass. If the coefficient of static friction between the mass on the table and the table is 0.342, what is the minimum value of the hanging mass that will start the system moving? 120 kg 980 kg 0 4.10 kg 3.42 kg Question 4 (1 point) Study the force system diagram pictured below and select the factor which would NOT influence the amount of kinetic friction.
