12) An object of mass m -12.0kg is aftached to a cord that is wrapped around a wheel of radius r =10.0cm W. The acceleration of the object down the frictionless incline is measured to be a-2.00m/s² and the ineline makes an angle 0-37.0° with the horizontal. Assuming the axle of the wheel to be frictionless, determine: (a) the tension in the rope (b) the moment of inertial of the wheel (c) the angular speed of the wheel 2.00s after it begins, starting from rest
