A 0.40 kg block can slide up and down a rough 10-m-high, 30-m-long slope. At the bottom, a stiff spring with spring constant 800 N/m is compressed 0.50 m and used to launch the block up the slope. The friction force on the block from the slope is 1.2 N. Use g = 10 m/s2. Match the answers with questions. the change in spring potential energy (AUsp) A. 18 J the change in gravitational potential energy (AUg) B. -40 J the change in thermal energy (AEth) C. -18 J the change in kinetic energy (AK) D. 36 E. 100 J F.-36 J G. 40 J H.-100 J 1. -24 J J. 24 J
