Suppose you are biking at a constant speed up a road inclined at 5° above the horizontal. You need to bike up this hill for 200 m in 2 minutes or less. There is an average drag force of 25 N as well. Calculate the minimum amount of power in hp your body must provide in order to make it up this hill in time. Assume 80 kg total mass of yourself and bike and 25% energy efficiency in your body. Define a system and draw energy state diagrams as part of your solution. Draw any necessary FBDs for forces.

A 1400 kg car starts from rest and accelerates uniformly to 19.5 m/s in 20s. a)Find the average power developed by the engine. Assume that air resistance remains constant at 344 N during this time. Answer in units of hp. b)Find the instantaneous power output of the engine at t = 20 s just before the car stops accelerating. Answer in units of hp.

Problem 1: A block of mass 10 kg is being pulled in a straight line alone the ground by a 60 N force directed 45 degrees above the horizontal. The kinetic coefficient of friction between the ground and the block is µK = 0.20. The box is pulled a distance of 6.0 meters and starts from rest. Find the speed of the box at the 6 meters. You must use the work energy-theorem and material from chapter 6 F
