An electric motor M is used to reel in cable and hoist a bicycle into the ceiling space of a garage. Pulleys are fastened to the bicycle frame with hooks at locations A and B, and the motor can reel in cable at a steady rate of 11 in./sec. At this rate, how long will it take to hoist the bicycle 8.0 feet into the air? Assume that the bicycle remains level. M Answer: t = A B sec
