Question

An 8.0 kg crate is pulled 5 meter up a 30 degree incline by arope angled 18 degrees above the incline. the tension in the ropeis 120 N and the crate's coefficent of kinetic friction on theincline is 0.25. How much work is done by tension, by gravity, and by thenormal force? What is the incres in thermal energy of the crate andincline?

Explanation / Answer

work done by normal force=0J work done by gravity=8*9.8*sin30*5 =196J work done by tension =120cos18*5=570.6J thermal energy= work done by friction=.25*30.81*5 =38.5J
