Determine the compression of the springs and their compressional forces in the case:
A majorette in a parade is performing some acrobatic twirlingsof her baton. Assume that the baton is a uniform rod of mass 0.120 kg and length 80.0 cm.
With a skillful move, the majorette changes the rotation ofher baton so that now it is spinning about an axis passing throughits end at the same angular velocity 3.00 rad/s as before. What is the new angularmomentum of the rod?
what will a spring scale read for the weight of a 55 kg woman in an elevator that moves upwards with constant speed of 6.0 m/s
A cubic block of wood, 10.0 cm on each side, floats at the interface between oil and water with is lower surface 1.50 cm below the interface. The density of oil is 790 kg/m(cubic). a) what is the gauge pressure on the upper surface of the block? b) what is the gauge pressure on the lower surface of the block? c) what is the mass and density of the block?
