... A man stands on a platform which is free to rotate on frictionless bearings. He has his arms extended with a huge mass m in each hand. If he is set into rotation with angular velocity 0 and then drops his hands to his sides, what happens to his angular velocity? (Assume that the man’s mass is negl ...

... The world’s most massive train ran in South Africa in 1989. Over 7 km long, the train traveled 861.0 km in 22.67 h. Imagine that the distance was traveled in a straight line north. If the train’s average momentum was 7.32 x 108 kg•m/s to the north, what was its mass? ...

... A baseball, mass m kg is moving horizontally at a velocity of v m/s when it is struck by a baseball bat. It leaves the bat horizontally at a velocity of v m/s in the opposite direction. (a) Find the impulse of the force exerted on the ball. (b) Assuming that the collision lasts for x ms, what is the ...

... for an un-normalized wavefunction. Expectation values For any physical property q there is an operator Q such that: Qψ=qψ or < q > = ∫ ψ* Q ψ dτ < q > is called the ‘Expectation Value’ of the property. It may be an exact value, for example for energy, or a ‘most probable value’, for example for posi ...
