Ah yes, but there is still a problem. This is what changes then:
2nd Givens: Vi: -7.3 m/s D:-51.15 Vf: 0(I'm not sure if this is right)
So I can get a time for when it's going down of 14 sec.
So I added the inicial velocities of the ball going up and going down and then divided it by 23.3(9.3...
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...
