Extra Problem 2. An object of mass m = 12.0 kg is attached to a cord that is wrapped around a wheel with a radius r = 10.0 cm (see Fig. 2). The acceleration of the object down the frictionless incline is measured to be a = 2.00 m and the incline makes an angle 0 = 37 with the horizontal. Assuming the axle of the wheel to be frictionless, determine: (a) The tension in the rope. (b) The moment of inertia of the wheel. (c) The angular speed of the wheel 2.00 s after it begins rotating (starting from rest)
