Unformatted text preview: 5. A bicycle wheel has a diameter of 66 cm. and a mass of 2.0 kg. Assume the wheel " has the characteristics of a hoop. A chain is driving the wheel over a 10.0 cm diameter sprocket that is attached to the wheel. If a resistive force of 100 N were applied tangent to the rim of the wheel, what force would be required on the chain to achieve an acceleration of 5.0 rad/$2? Fa = m/WZ[5. MEGA) ; 2 {.53)7[§J%/06633,l '5 6. A bucket with a mass of 3.0 kg is suspended by a rope that is wrapped around a cylinder. The cylinder has a mass of 5.0 kg, a radius of 0.6 m and is free to rotate on a frictionless axle. If the rope does not slip on the cylinder and the bucket is released from rest, what is the velocity of the bucket after it has fallen 4.0 m? ...
