Question

1. A 12.0 kg box slides down a metal chute at a warehouse where the coefficient of kinetic friction is $\mu_k$ = 0.246. The chute can be modeled as a flat ramp that is 1.00 m high and makes an angle $\theta$ = 37.5$^\circ$ with the horizontal, followed by a long horizontal section. (a) How fast is the box going at the bottom of the ramp? (b) How far can the box slide on the horizontal section? (c) After the box has slide down the ramp and an additional 0.5 m on the horizontal section, how much energy has been converted to heat?

Step 1

The initial potential energy of the box at the top of the ramp is given by mgh, where m is the mass of the box (12.0 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height of the ramp (1.00 m). The final kinetic energy of the box at the bottom Show more…
