I got this problem:
A ball is rolled up a constant slope with an initial velocity of 11.0 m/s and after 9.3 s the ball is rolling down the slope with a velocity of 7.3 m/s. What is the acceleration of the ball on the slope.
Here's what I tried: I divided the problem in 2 for the ball going up, and the ball going down.
1st Givens: Vi: 11 m/s Vf: 0 t:9.3
2nd Givens: Vi: 7.3 m/s Vf :0
I then got the displacement of half of the slope from the first set of givens, which gave me 51.15. That's where I got stuck. I tried getting a acceleration for both sides of the slope and then averaging, but that wasn't right.
Please help
