Question

Block 1 with mass m1=4.68 kg rests on a horizontal ledge with negligible friction. This block is then attached to a string that passes over a pulley, and the other end of the string is attached to the hanging block 2 of mass m2=2.34 kg, as shown.

  • The pulley is a uniform disk of radius 10.95 cm and mass 1.600 kg. Calculate the speed of block 2 after it is released from rest and falls a distance of 2.71 m.
  • What is the angular speed of the pulley at the instant when block 2 has fallen a distance of 2.71 m ?
