. 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=v_{0}-gt

8=v_{0}-60

v_{0}=68

deltax =v_{0}t - .5gt^{2}

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=v_{0}-60

52=v_{0}

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?
