A uniform rod of length L1 = 1.9 m and mass M = 3.0 kg is supported by a hinge at one end and is free to rotate in the vertical plane. The rod is released from rest in the position shown. A particle of mass m is supported by a thin string of length L2 = 1.5 m from the hinge. The particle sticks to the rod on contact. After the collision, ?max = 30°. find m? how much energy is dissipated from the collision?
A merry-go-round (carousel) with a moment of inertia of 594 kg·m2, is initially rotating horizontally at 2 rad/s about a frictionless axis through its center. find that coefficient of kinetic friction
what is the lumberjack's speed relative to the shore? Neglect friction between the log and the water.
A hypodermic syringe is attached to a needle that has an internal radius of 0.303 mm and a length of 3.02 cm. What must the pressure of the fluid in the syringe be in order to inject the solution at a rate of 0.253 mL/s
Consider three identical metal spheres, A, B, and C. Sphere A carries a charge of +8q. Sphere B carries a charge of -q. Sphere C carries no net charge. Spheres A and B are touched together and then separated.
