We want to slide a 10.0-kg crate up a 3.0-m-long ramp inclined at 30.0° A worker, ignoring friction, calculates that he can do this by giving it an initial speed of 6.0 m/s at the bottom and letting it go. But friction is not negligible; the crate slides only 2.2 m up the ramp, stops, and slides back down see the Figure.
