(c) What is the work done by friction in the parking lot? (d) Find the magnitude of the average friction force. SOLUTION : (a) At point A EA = mgh = (90 kg) 9.80 m/s2 (15 m) = 13230 J At point B‚ James Bond is at rest so‚ EB = 0 (b) Using conservation of energy: EA = EB ⇒ EA = EC ⇒ mgh = mg h 1 + mv 2 ⇒ 2 2 B ⇒ vB = vC = gh = 2gh = 9.80 m/s2 (15 m) = 12.1 m/s 2 9.80 m/s2 (15 m) = 17.1 m/s 1 2 mgh = mvC 2 (c) Using conservation of energy: EC + Wf C→D = ED ⇒ Wf C→D = ED − EC = -13230
