Question

An object of mass 

M = 13.0 kg

 is attached to a cord that is wrapped around a wheel of radius 

r = 10.5 cm

 (see figure). The acceleration of the object down the frictionless incline is measured to be 

a = 2.00 m/s2

 and the incline makes an angle 

? = 37.0°

 with the horizontal. Assume the axle of the wheel to be frictionless.

M
(a) Determine the tension in the rope.
(b) Determine the moment of inertia of the wheel.
|kg •m2
(c) Determine the angular speed of the wheel 2.50 s after it begins rotating, starting from rest.
