Energy ConversionsEnergy Conversions 1st Conversion: Ball rolls down the first ramp changing energy from potential to kinetic. Mgh=(1/2)mv^2+mgh (5g)(9.81m/s^2)(.2699m)=(.5)(5g)v^2+(5g)(9.81m/s^2)(.2223m) V=.966m/s  2nd Conversion: Ball hits the second ramp causing energy loss. (1/2)mv^2=mgh+Eloss (.5)(5g)(.966m/s)^2=(5g)(9.81m/s^2)(.0254m)+Eloss Eloss=.109J

3rd Conversion: Ball rolls down the second ramp. Mgh=(1/2)mv^2+mgh (5g)(9.81m/s^2)(.2223m)=(.5)(5g)v^2+(5g)(9.81m/s^2)(.0191m) V=2.00m/s
