It takes 130 minutes for a middle-aged physics professor to ride his bicycle up the road to Alpe d'Huez in France. The vertical height of the climb is 1,120 m, and thecombined mass of the rider and bicycle is 94 kg. What is the bicyclist's average power output?Show My Work(Optional) 132.3WPowerPEt9388404=132.274910.–/7.14 pointsOBInPhys7 3.Q.013.When you throw a ball, the work you do to accelerate it equals the kinetic energy the ball gains. If you do twiceas much work when throwing the ball, does it gotwice as fast? Explain.
