Calculate vr, the speed of the ball when it leaves the launching ramp. Express the speed of the ball in terms of k, s, m, g, y, and/or H.(adsbygoogle = window.adsbygoogle || []).push({});

i know it will contain m, y and k

also

With what speed will the ball hit the floor? Express the speed of the ball in terms of k, s, m, g, y, and/or H.

i am so confused when it comes to creating these "expressions" i dont even know where to begin or what the heck to do.
