1. The problem statement, all variables and given/known data The diagram shows a kid jumping off a snow pile into the grown that is also covered with snow. So the kid is jumping up and then lands on the ground. https://scontent-arn2-1.xx.fbcdn.net/hphotos-xpf1/v/t34.0-12/12380374_1234806623215387_1066477107_n.jpg?oh=fe84392440a1ddbf0eebf557109d56ec&oe=5677CAA8 The question is: how tall is the snow pile if the ground is 0 m? 2. Relevant equations S=v0t + (at^2)/2 3. The attempt at a solution I am thinking that the kid is at its highest point when the velocity is zero and t=0.4. It takes 0.4 seconds up and also 0.4 seconds down to the level where the snow pile was at. so the snow piles height is from 0.8 seconds to 1,2 seconds. 1.2-0.8=0.4 s= -4*0.4 + (9.82 * 0,4^2)/2 = - 0,8144 What went wrong in my assumptions or solution?
