Paco rode his skateboard up a ramp for a distance of 3.8 meters. If the ideal mechanical advantage of the ramp is 2, how far above the ground was Paco?

The ideal mechanical advantage of an inclined plane or ramp is equal to the length of incline divided by height of the inclined plane. in equation

MA = L / H

since the ideal mechanical advantage of the given inclined plane is 2 and the length of inlcine is 3.8 m

MA = L / H

H = L / MA

H = 3.8 / 2

H = 1.9 m was paco above the ground
