Answer #1

height descended dex= gin. from Law of conservation of energy Total energy restored by Spring = Potential energy I gained byache here, wang = 3016 { (200) (0)2 = (30) h * h = 120 in * Now , Distance trowelled = 4 = 60 in acceleration 2-9- UPO, V=? wNote that h/2 includes the distance upto which spring and block combinedly move up, because they start to travel from zero combined velocity.

Any doubts, let me know. I will help and then rate
