Question #181216

A girl pushes a 50-kg box up a ramp 25 m in length and inclined at 10° with the horizontal. What potential energy change does the crate experience?

Expert's answer

Find height of the ramp above the floor:

"h=L\\sin\\theta."

Potential energy change:

"W=mgh=mgL\\sin10\u00b0=2127\\text{ J}."
