1. The problem statement, all variables and given/known data . A ball is thrown straight up at t=0. It is found to be falling with a speed of 8 m/s at t= 6 sec. Find the displacement of the ball. 2. Relevant equations 3. The attempt at a solution v=v0-gt 8=v0-60 v0=68 deltax =v0t - .5gt2 delta x = (68*6)- 5*36=228 but it says the answer is -132 am i wrong or is it wrong? Edit: nvm I got it it was supposed to be -8 -8=v0-60 52=v0 deltax=52*6 - .5*10*36 = 132 uhm it seems I messed up again this time I got a plus why isn't it a minus?
