A student wearing frictionless in-line skates on a horizontal surface is pushed by a friend with a constant force of 50.0 N. How far must the student be pushed, starting from rest, so that her final kinetic energy is 350 J?

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.
