A 60.0 kg woman stands at the rim of a horizontal turntablehaving a moment of inertia of 500 kgm^2 and a radius of 2.00m. The turntable is initially at rest and is free to rotateabout a frictionless, vertical axle through its center. Thewoman then starts walking around the rim clockwise (as viewed fromabove the system) at a constant speed of 1.50 m/s relative to theEarth.
a) In what direction and with what angular speed does theturntable rotate?
b) How much work does the woman do to set herself and theturntable into motion?

A two-slit pattern is viewed on a screen 1.10 m from the slits. If the two third-order minima are 21.0 cm apart, what is the width of the central bright fringe
If a car takes a banked curve at less than a given speed, friction is needed to keep it from sliding toward the inside of the curve (a real problem on icy mountain roads).
A block that has a mass M = 4.25 kg is hanging at rest on a light string. A projectile with a mass m = 250 g moving horizontally strikes M and sticks to it. The block and its projectile swing up and the center of mass rises a distance h = 12.0 cm. Th..
