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/s

On a windy day, you decide to use a small homemade parachute to travel up a 7.4 degree hill on your frictionless rollerblades. You begin from rest at the bottom of the hill and travel a distance of 23 meters up the hill (measured along the incline), reaching a speed of 14 m/s. You have a mass of 60 kg. Determine the force the wind exerts on the parachute, assuming the force the wind exerts is parallel to the surface of the incline. Use conservation of energy.
