In figure, a wheel of radius 0.30 m is mounted on a frictionless horizontal axle. A massless cord is wrapped around the wheel and attached to a 3.0 kg box that slides on a frictionless surface inclined at angle θ = 29° with the horizontal. The box accelerates down the surface at 1.9 m /s 2. What is the rotational inertia of the wheel about the axle? (Your answer must be in units of kg.m 2 and include 3 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g=9.80 m /s 2.)
To find the rotational inertia I of the wheel first we have to calculate Tension in the cord and then using tension value calcualate rotational inertia of wheel upto 3 digits after decimal point.
