A mover pushes a 4.21 kg box with a 36.6 N constant horizontal force up a 10.0° ramp that has a height of 1.57 m. If the ramp is assumed to be frictionless, find the speed of the box as it reaches the top of the ramp using work and energy.

Answer 1

work done= force*distance where force is vertical force
force=36.6-mg*sin10 parallel to plane
distance=1.57 along plane
force*distance=finalKE+finalPE
final KE=1/2 mv^2
final PE=1.57*mg
