Question

A block is released from rest on a frictionless incline as shown. When the moving block is in contact with the spring and compressing it, what is happening to the gravitational potential energy \( U_{\text {grav }} \) and the elastic potential energy \( U_{\text {el }} \) ? A. \( U_{\text {grav }} \) and \( U_{\text {el }} \) are both increasing. B. \( U_{\text {grav }} \) and \( U_{\text {el }} \) are both decreasing. \( \_\_\_\_ \) C. \( U_{\text {grav }} \) is increasing; \( U_{\text {el }} \) is decreasing. D. \( U_{\text {grav }} \) is decreasing; \( U_{\text {el }} \) is increasing. E. The answer depends on how the block's speed is changing.
