Question

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?

Answer 1

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
