I got this problem:(adsbygoogle = window.adsbygoogle || []).push({});

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/sVf: 0t:9.3

2nd Givens:Vi:7.3 m/sVf:0

I then got the displacement of half of the slope from the first set of givens, which gave me51.15. 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
