Q. A light rope is wrapped several times around a large wheel with a radius of 0.400 m. The wheel rotates in frictionless bearings about a stationary horizontal axis. The free end of the rope is tied to a suitcase with a mass of 15.0 kg. The suitcase is released from rest at a height of 4.00 m above the ground. The suitcase has a speed of 3.50 m/s when it reaches the ground.
Calculate the angular velocity of the wheel when the suitcase reaches the ground. Calculate the moment of inertia of the wheel.
A car of mass 1110 kg travels at a speed of 20 ms-1 along a straight road. The driver sees a red traffic light ahead, and applies brakes. The coefficient of friction between the car tyres and the road is 0.83. Take the acceleration due to gravity to ..
