A cyclist travels from point A to point B in 10 mm. During the first 2.0 mm of her trip, she maintains a uniform acceleration of 0.090 m/s². She then travels at constant velocity for the next 5.0 nun. Next, she decelerates at a constant rate so that she cons to a rest at point B 3.0 mm later. (a) Sketch the velocity- versus-tine graph for the trip.

44. A metal ramp 6.00 m long is tilted 10.0° and is used to load and unload a moving van. Suppose a 20.0 kg box is pushed up the ramp and it slides with a friction coefficient of 0.30. The ramp can be viewed as a "machine" where the useful output is the potential energy gain of the box and the input is the physical work done by the person doing the pushing. (a) Determine the efficiency of the ramp. (b) Determine the ratio of the force needed to lift the box without the ramp to the force needed to push it along the ramp (this is called the mechanical advantage).
