Homework Statement
A ball rolls up a straight incline. The dots in the diagram represent the position of the ball every 4 seconds.
(The fourth dot is not intended to represent the turnaround point; the ball might still be on the way up at that
point.) The instantaneous velocities at the second and third dots are as given in the diagram.
a. Determine the velocities at the locations of the first and fourth dots and label them on the diagram. (2 points)
b. Determine how far the ball travels between the second and third dots. (3 points)

Homework Equations
aavg= Delta V/ Delta T
The Attempt at a Solution
I am kind of stumped at this problem and not sure where to begin or how to get where I'm trying to go, all I could think to do was this...then I wasn't sure where to go from there.
(5m/s2 + 7m/s2) / 2 = Delta V/(8s-4s)
Delta V = 24m/s
Please help! thank you
