work = pulling force in direction of motion * distance like period, the friction and all are irrelevant. work = 161 cos 35 * 13.5 If there are more parts like how fast does it go or something, the rest matters, but that is all you need to know for the question you asked.

**physics**

mass does not matter, call it m normal force = m g cos 44 max friction force up slope = .27 m g cos 44 gravity force down slope = m g sin 44 so m g sin 44 - .27 m g cos 44 = m a (sin 44 - .27 cos 44) 9.81 = a
