If block 2 is moving up the incline at 2 constant speed, what is the mass mj of block 1? 1 kg M¡ =Multiple-Concept Example 5 reviews many of the concepts that play a role in this problem. An extreme skier, starting from rest, coasts down a mountain that makes an angle of 32.5° with the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.244. She coasts for a distance of 12.3 m before coming to the edge of a cliff. Without slowing down, she skis off the cliff and lands downhill at a point whose vertical distance is 3.67 m below the edge.

- Starting from rest, a 30.6 kg child rides a 8.50 kg sled down a frictionless ski slope. At the bottom of the hill, her speed is 6.4 m/s. If the slope makes an angle of 15.1° with respect to the horizontal, how far along the hill did she slide on her sled?A worker pushes a 35.0-kg package on a horizontal roller-belt conveyor until it reaches a certain speed. The package then coasts on the horizontal conveyor, all the while slowing down, until it comes to a complete stop after moving 1.20 m. While the package is coasting on the conveyor, the opposing friction force averages 6.00 N. Use the WET to find the speed of the package after the worker pushes it and just as it begins to coast. 0.625 m/s 0.759 m/s 0.600 m/s 0.510 m/s 0.802 m/s 0.641 m/sA truck with a mass of 750 kg is traveling along a wet road at 30.0 m/s The driver slams on the brakes and skids to a stop.
