A 0.40 kg block can slide up and down a rough a 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. v the change in spring potential energy (AUSD) A. -36 J - v the change in gravitational potential energy (AUg) B. -18 ) C. 18) . v the change in thermal energy (AEth) D. 36 . v the change in kinetic energy (AK) E. -40J F. -100J G.-24 J H. 24J I. 40J J. 100J
