An Atwood's machine has one block of m1 = 0.150 kg and the other is of m2 = 0.210 kg. The disk pulley, which is mounted in horizontal, frictionless bearings, has a radius of 5.0 cm. When released from rest, the heavier block is observed to fall Δy = 80.0 cm in 4.0 sec.

The moment of inertia for the pulley is: kg m2.

  • Suppose you are a space traveler, and you land on the surface of a strange new planet

    Suppose you are a space traveler, and you land on the surface of a strange new planet. As stated in your Starfleet Manual, your first job is to measure the acceleration due to gravity, g, on this planet. You construct an "Atwood machine", which consists of two masses connected to a pulley by a string of negligible mass, as shown in the figure. One of the masses is m1 = 50.0 kg and the other is m2 = 39.0 kg....
