A students have built a cart of mass M with an engine that can propel it with a non-constant force. In a test run, they launch the cart on a horizontal surface from rest. While the surface is horizontal, the cart’s engine provides a force F(x)=Fo+cx3 in the direction of the cart’s motion, where x is the distance traveled, and Fo and c are positive constants. Due to a design flaw, the engine stops working after the cart has traveled a distance D, as soon as the cart encounters a frictionless incline that makes an angle θ with the horizontal.

Use the Work-Kinetic Energy Theorem to derive an expression for the speed of the cart when it has reached a vertical height H above the starting point.

Force multiplied in to perpendicular distance such as that applied on levers results in torque which caused the lever or the plane on which force is applied to turn or rotate.
