A cord is wound around the circumference of a bicycle wheel (without tyre) of diameter 1 m . A mass of 2 kg is tied at the end of the cord and it is allowed to fall from rest. The weight falls 2 m in 4 s . The axle of the wheel is horizontal and the wheel rotates which its plane vertical. if g = 10 ms^(-2) , what is the angular acceleration of the wheel ?
