A metal ring having an outside radius of 38.0 cm, and an inside radius of 30.5 cm, has a mass of 15.0 kg. The ring falls off the back of a speeding truck, and rolls without slipping at a speed of 45.0 Km/hr.
A. What is the moment of inertia of the ring?
B. What is the total kinetic energy of the ring?
C. If friction causes the ring to stop in 500m, how much work did friction do?
A blue car with mass mc = 442 kg is moving east with a speed of vc = 22 m/s and collides with a purple truck with mass mt = 1213 kg that is moving south with a speed of vt = 12 m/s. find the magnitude of the initial momentum of the car
If the particle is released from rest at the midpoint C, s=100mm, and the acceleration is measured as a= (4s) m/s2 , where s is in meters, evaluate the velocity of the particle when it reaches plate B, s=200mm, and the time it needs to travel C to ..
