A solid sphere and a solid cylinder with the same mass and radius roll down an inclined plane without slipping. Which one will reach the bottom of the incline first. Explain why. Assume friction is negligible for both.
Water flows through a Venturi meter with a pipe diameter of 10.0 cm and a constriction diameter of 5.6 cm. The U-tube manometer is partially filled with mercury.
A 64 kg person on skis is going down a hill sloped at 30° from the horizontal. The coefficient of friction between the skis and the snow is 0.15. What would be the magnitude of acceleration.
You are trying to slide a refrigerator across a horizontal floor. The mass of the refrigerator is 188kg, and you require to exert a force of 347N to make it just begin to move. What is the coefficient of static friction between floor and refrigera..
A massless string runs around two massless, frictionless pulleys. An object with mass m = 12.20 kg hangs from one pulley. A force F is exerted on the free end of the string. What is the magnitude of the force F if the object is lifted at the constant..
Damped forced oscillations, A single stage vibration isolation system consists of a heavy granite slab (100 kg) sitting on legs which act as a vertical damped spring. The "Q" (Quality Factor) of the system is 8.0, and the velocity damping coeffici..
