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 2.0kg box that slides on a frictionless surface inclined at angle 8 = 23 with the horizontal. The box accelerates down the surface at 1.9 m /s?.What is the rotational inertia of the wheel about the axle? (Your answer must be in units of kg.m? and include 3 digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take g=9.80 m /s2)
