A small mass m on a string is rotating without friction in acircle. The string is shortened by pulling it through the axisof rotation without any external torque, Fig. 8–39. Whathappens to the tangential velocity of the object?(a) It increases.(b) It decreases.(c) It remains the same.
An asteroid of mass 1.5×105 kg , traveling at a speed of 40 km/s relative to the Earth, hits the Earth at the equator tangentially, and in the direction of Earth's rotation, and is embedded there.
Use angular momentum to estimate the percent change in the angular speed of the Earth as a result of the collision.
Two particles, each with mass m, are fastened to each other and to a rotation axis by two rods, each with length L and mass M, as shown in fig 9-44. The combination rotates around the rotation axis with angular velocity w.
What is the moment of inertia of the combination about the axis at point O?
