Show your work for each part of the question. tinu MO 0.4 kg Rough surface A block with a mass of 0. 4 kg starts from rest while compressed 0. 10 magainst a spring. The constant of the spring is 2000 N/m . When released, the block slides to the right along a frictionless horizontal surface and then moves through loop that is 2m above the ground at the highest point. The block then slides to stop along a rough horizontal surface. a. Determine the speed of the block the moment the compression distance is 0. IKDX 1 (2000 ) (0 ) b. Determine the speed of the block at the top of the loop. 4 ( + 0) 2 = 5 m v 16 = 1 4 . V 2 (20 00 ) ( . 1) = 100 " mv2 - wole how sit us off/items V = 6. 3245 1 = 6- 320 2 1 1 .4 ) v 2 = 100 c.
