A wheel of radius 0.20 m is mounted on a frictionless horizontal axis. The rotational inertia of the wheel about the axis is 0.050 kgm2. A massless cord wrapped around the wheel is attached to a 2.0 kg block that slides on a horizontal frictionless surface. If a horizontal force of magnitude P=3.0 N is applied to the block , what is the magnitude of the angular acceleration of the wheel? Assume the cord does not slip on the wheel.

Question

A wheel of radius 0.20 m
is mounted on a frictionless horizontal
axis. The rotational inertia of the
wheel about the axis is 0.050 kg
m2.
A massless cord wrapped around
the wheel is attached to a 2.0 kg
block that slides on a horizontal frictionless surface. If a horizontal
force of magnitude P=3.0 N is applied to the block , what is the magnitude of the angular acceleration of the
wheel? Assume the cord does not slip on the wheel.
