Homework Answers
From work energy theorem , change in kinetic energy or potential energy is equals to work done.
In case of B,C and D , change in heights are equal hence work done will be equals to each other that will be less than work done by A.
Hence option (D.) is correct.

Consider the portion of the motion of block 1 during which it moves a distance L1, and the portion of the motion of block 2 during which it moves a distance L2. Each block is displaced the same vertical distance Z. The hand pushes parallel to the incline with the same magnitude of force FBH in both cases. Block 1 moves with constant speed Ramp Ramp 2 A....

1) A cart for hauling ore out of a gold mine has a mass of 447 kg, including its load. The cart runs along a straight stretch of track that climbs a shallow 4.63∘ incline. A donkey, which is trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 436 N force for a distance of 115 m by means of a rope that is parallel to the...

Consider the following three cases 1. The finger is pushing but not hard enough. Neither block moves 2. The finger is pushing hard enough that the two blocks are speeding up 3. The blodies have sped up, and are now moving at a constant speed. The finger still has to push to keep them going at a constant velodty. In all cases where the blocks are moving, they are moving together. (Block is not sliding on block A.) Block A...
