    Calculating Speed on an Inclined Plane | Mechanical Energy #2

    A 19 kg box starts at rest and slides down a frictionless ramp. The length of the ramp is 4.5 m and the height above the ground at the top is 1.3 m. How fast is the box moving at the bottom of the ramp? Unsure of inclined planes...help with formulas, etc.?

    Mechanical Energy: Calculating Work w/ Box, Ramp & Friction

    How much work was required to push a 36 kg box from the bottom of a ramp a distance of 10 m to the top of 1.7 m above the ground if the friction force between the box and the ramp is 20 N? Help? Formulas?
