(answered) – 1) A 70.5-kg skier coasts up a snow-covered hill that makes anDescriptionSolution downloadThe Question1) A 70.5-kg skier coasts up a snow-covered hill that makes an angle of 34.1 ? with the horizontal. The initial speed of the skier is 8.27 m/s. After coasting a distance of 1.48 m up the slope, the speed of the skier is 4.73 m/s.(a)Find the work done by the kinetic frictional force that acts on the skis.(b)What is the magnitude of the kinetic frictional force?2)?A golf ball strikes a hard, smooth floor at an angle of 33.2 ? and, as the drawing shows, rebounds at the same angle. The mass of the ball is 0.0625 kg, and its speed is 42.0 m/s just before and after striking the floor. What is the magnitude of the impulse applied to the golf ball by the floor??(Hint: Note that only the vertical component of the ball’s momentum changes during impact with the floor, and ignore the weight of the ball.)
