A man pushes two boxes with the same amount of force (because they look identical and he can’t see inside them). The boxes are made of the same material, but one is full and the other is empty. Which box will speed up more?

Two blocks are positioned on surfaces, each inclined at the same angle of 47.2 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 7.58 kg, and this time there is NO friction. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2? 1 7.71 kg 2 11.57 kg 3 6.08 kg 4 17.36 kg

Two buckets of sand hang from opposite ends of a rope that passes over an ideal pulley. Onebucket is full and weighs 120 N; the other bucket is only partlyfilled and weighs 63 N. (a) Initially, you hold onto the lighterbucket to keep it from moving. What is the tension in the rope?(b) You release the lighter bucket and the heavier one descends.What is the tension in the rope now? (c) Eventually the heavierbucket lands and the two buckets come to rest. What is the tension in the rope now? Show your work and explain

Two blocks are positioned on surfaces, each inclined at the same angle of 55.7 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 2.73 kg, and this time there is NO friction. What is must be the mass of the white block if both blocks are to slide to the LEFT at an acceleration of 1.5 m/s^2? a. 2.65 kg b. 3.97 kg c. 1.23 kg d. 5.96 kg
