Question

If a group of workers can apply a force of 1000 newtons to move a crate 20.0 meters on a frictionless ramp: How high up a ramp will the crate travel?

Answer 1

That's going to depend on the mass of the crate. They'll be able to push a crate full of pingpong balls really high, but they may not be able to even budge the crate at all if it's full of bricks.
