Humans can produce an output power as great as 20 W/kgW/kg during extreme exercise. Sloths are not so energetic. At its maximum speed, a 4.0 kgkg sloth can climb a height of 6.0 mm in 2.0 minmin. (Figure 1) a. How much work does the sloth do against gravity to climb 6.0 mm? b.What is the sloth’s specific power output during this climb? Express your answer in watts per kilogram.
Piano movers wish to load a truck using a ramp from the ground to the rear of the truck. One of the movers claims that less work would be required if they used a ramp at an angle above the ground. Another mover claimed that it is less work to just pick it straight up. Who is right? possible answers: -there is not enough information to make a claim -it is less work using a ramp -it is the same amount of work Wrong answer:is it more work using a ramp (homework question)
