Physics

A 0.25 kg block slides down a ramp that is 0.6 m tall, 0.8 mlong and has a diagonal length of 1.0 m. The block starts at restand arrives at the bottom with a speed of 1.3m/s. a.) How much heatwas created by friction? b.)What is the average frictional forceacting on the block? At what rate is kinetic energy beingdissipated into heat near the bottom of the ramp? c.)Instead of ablock, a cart with a mass of 0.33 kg rolls without any frictionallosses. It collides with a horizontally mounted spring at thebottom of the ramp. If the spring has a spring constant of 215 N/m,how far will it be compressed. d.)Draw energy bar graphs for thefollowing four moments: a. the moment of release, b. halfway downthe ramp, c. at the base of the ramp d. when the spring has reachedmaximum compression.
