The block is released and slidesdown until it hits a spring and compresses the spring a maximum distance of x as shown in thediagram above. A student believes that if the block is lifted to a height of 2h and released, thenthe spring will be compressed to a maximum distance of 2x because increasing thegravitational potential energy increases the elastic potential energy.a. Which aspects of the student's reasoning, if any, are correct? Explain how you arrived atyour answer.b. Which aspects of the student's reasoning, if any, are incorrect? Explain how you arrived atyour answer.c. Develop an expression for the new distance the spring is compressed, x'. Express youranswer in terms of x.d. Instead of the block starting from h hitting the spring directly, it first hits another identicalblock and the two blocks stick together before they hit the spring. Will the spring becompressed more than, less than or the same as it was before the second block wasadded?more thanless thanthe sameExplain your reasoning. 2. Block A of mass M is on a horizontal, frictionless tabletop with height H and is placed against aspring of negligible mass and spring constant k. The other end of the spring is attached to awall. The block is pushed toward the wall until the spring has been compressed a distance x.The block is released and follows the trajectory shown striking a target on the floor that is adistance D from the edge of the table. Air resistance is negligible.a. Derive an expression for the speed of the block as it leaves the table.b. Derive an expression for the speed of the block right before it hits the floor.The frictionless table is now inclined above the horizontal. The right end of the table is at thesame height as the original setup, while the left end is lower than the original setup. Block B ofmass M is placed against the same spring. The spring is compressed the same distance x andthe block is released.c. Compare the work done by the spring in this scenario W2 to the work done by the spring inthe first scenario, W1.W; < W2W;> W2W; = W2Explain your reasoning in a brief response.d. Compare the velocity of block A to the velocity of block B when they leave the table.VA< VBVA> VBVA = VBExplain you reasoning in a paragraph-length response.
