Homework Equations
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?
