# No, wait, don't let go!

You are pushing a piano up a ramp and into a truck. The ramp is $$5~\mbox{m}$$ long and the truck bed is $$1~\mbox{m}$$ high. Nearing the top, you slip, releasing your hold on the piano, which begins to slide back down the ramp. If there is no friction between the piano and the ramp, then what is the magnitude of the acceleration of the piano in $$\mbox{m/s}^2$$?

Details and assumptions

• The acceleration due to gravity is $$-9.8~\mbox{m/s}^2$$.
