Unformatted text preview: 1. A rope is wrapped around a wheel of diameter, 50 cm. The wheel is mounted with
frictionless bearings on an axle through its center. A block of 15 kg is suspended
from the end of the rope. When the system is released from rest the block falls 5.0 m
in 2.0 s. a. (5 points) What is the linear acceleration of the falling block? b. (5 points) What is the angular acceleration of the wheel, assuming the rope
doesn’t slip on the wheel? c. (5 points) What is the tension in the rope? d. (Spoints) What is the moment of inertia of the wheel? Note, this should be calculated from data in the problem and not from the formula for I of a disk or a
hoop. )(zvot wiécﬂpz El. ...
