A rope is wrapped around a wheel of diameter, 50 centimeter. The wheel is mounted with frictionless bearings on an axle through its center. A block of 15 kilogram is suspended from the end of the rope. When the system is released from rest the block falls 5.0 meter in 2.0 second.
a) Find the linear acceleration of the falling block?
b) Find the angular acceleration of the wheel, suppose the rope does not slip on the wheel?
c) Find the tension in the rope?
