A potter's wheel (a solid, uniform disk) of mass 6.0kg and radius 25cm spins about its central axis with an angular speed of the wheel is 15rpm. A 0.50kg lump of clay is moving with a horizontal velocity of 2m/s hits the wheel and sticks at the edge. Find the new angular speed of the system in rpm.
A high-pass RC filter is connected to an AC source with a peak voltage of 10.0 V. The peak capacitor voltage is 6.0 V. What is the peak resistor voltage
A 53 kg skier skis directly down a frictionless slope angled at 12° to horizontal. Choose the positive direction of the x axis to be downhill along the slope.
A pulley 18 in diameter is free to rotate about the horizontal axle. A 220 mass and a 420 mass are tied to either end of a massless string, and string is hung over the pulley.
The leg and the cast in Fig 4.20 below weigh 220 N (w1). Determine the weight w2 and the angle α needed so that no force is exerted on the hip joint by the leg plus the cast.
A 23 kg body is moving in the direction of the positive x axis with a speed of 292 m/s when, owing to an internal explosion, it breaks into three pieces.
