A 2.1 kilogram mass is connected to a spring with spring constant k = 150N/m and unscratched length 18 centimeter. The pair is mounted on a frictionless air table, with the free end of the spring attached to a frictionless pivot. The mass is set into circular motion at 1.4m/s. Evaluate what the radius of its path.
Coin is placed 14.0 from the axis of the rotating turntable of variable speed. When the speed of the turntable is slowly increased, the coin remains fixed on turntable until a rate of 40.0 (revolutions per minute) is reached, at that point the coin s..
A 100 kg crate is being pushed across the horizontal floor by a force that makes an angle of 30.0° below the horizontal. The coefficient of kinetic friction is 0.230. What must be the magnitude of, so that the net work completed by it and the kinetic..
A 75 , 33 long rod hangs vertically on a frictionless, horizontal axle passing by its center. A 12 ball of clay traveling horizontally at 2.6 hits and sticks to the very bottom tip of the rod.
