... 13. Loss in PE by Y = gain in PE of X + gain in KE by X plus Y Gain in KE of the system = 5 (10) (2) – 4(10)(2 sin 30o) = 60 J 14. From A to B, friction acts down the incline. Work done by friction = Fs = 2.6 x AB cos 180o = -2.6 x 10/sin 30o = - 52 J From B to C, friction acts up the incline . Work ...

... you are spinning at full speed, the floor is dropped out from underneath you, but you don’t fall with it. If the coefficient of friction between you and the wall is 0.8, how fast does the drum need to be spinning for you to stay up when the floor drops? Guess your mass as best you can to use in the ...
