Repeat for a $15$ degree incline

What was the average speed of the ball after it left the ramp? $v_{\text{a}\text{v}\text{e}}=\frac{2\frac{L}{5}}{}t=$

What was the average acceleration over the length of the ramp? $a_{\text{a}\text{v}\text{e}}=$

Did anything not match your expectations based on your work in the prelab?

If so$,$ what do you think cause this?

Draw a velocity vs$.$ time profile for the four experiments you did for the ball. $($Use the

back of the lab sheet$)$

Draw an acceleration vs$.$ time profile for the four experiments you did.
