... •Power output of the Crab pulsar, in radio and X-rays, is about 6 x 1031 W (which is about 150,000 times the power output of our sun). Since the pulsar is out of nuclear fuel, where does all this energy come from ? • The angular speed of the pulsar, and so the rotational kinetic energy, is going dow ...

... We assume that mB mA , and so mB will accelerate down, mA will accelerate up, and the pulley will accelerate clockwise. Call the direction of acceleration the positive direction for each object. The masses will have the same acceleration since they are connected by a cord. The rim of the pulley wi ...

... 7 A cup of coffee of mass 250 grams sits on a table in a train carriage. The train accelerates at 1.2 ms–2 out of a station. a Draw the forces acting on the cup of coffee. b If the cup does not slip, find the value of the friction force acting on the cup of coffee. c If the cup is just about to slip ...
