- A string is wrapped many times around a pulley and is connected to a block with mb = 4.641 kg that is hanging vertically. The pulley consists of a wheel of radius 43.11 cm and mass mp constructed with spokes that have negligible mass. What is the magnitude of the acceleration of the block? Submit Answer Tries 0/99 6.455 kg тр тьAm1= 19.0-kg object and a m 2 = 9.0-kg object are suspended, joined by a cord that passes over a pulley with a radius of R = 30.0 cm and a mass of M = 3.00 kg as seen in the Figure. The cord has a negligible mass and does not slip on the pulley. The pulley rotates on its axis without friction. The objects start from rest d = 5.00 m apart. Treat the pulley as a uniform disk, and determine the speeds of the two objects as they pass each other. (Your result must be in units of m /s and include 2 digit after the decimal point.
