Objective: SWBAT determine the force on an object (Review of Forces)
Warm Up: A 2 kg mass is pushed 0.5 m into a spring with spring constant 200 N/m on a frictionless horizontal surface. Upon release, the mass travel across the surface until it encounters a rough incline. The mass moves up the incline and stops at a height of 1 m above the horizontal surface.
a. How much work must be done to compress the spring initially?
b. What is the speed of the mass at the base of the incline.
c. How much work was done by friction on the incline?
