A solid ideal rod (stick, pole) AB with the ends marked with letters A and B moves so that its end A has a velocity with the velocity magnitude Va and direction at an angle a to the direction AB. The velocity Vb of its end B is directed at an angle B to the direction AB. What is the speed of the end B? O Va cos a / cos B O Va cos (a - B) O Va sin (a - B) O Va cos a cos B O Vą cos a i sin B O Va cos a sin B O Va sin (a + B) O sin a cos 6

The momentum of an object is given by multiplying its mass and velocity. Momentum is a property of any object that moves with mass. The only difference between angular momentum and linear momentum is that angular momentum deals with moving or spinning ob…

The idea of moments is an important concept in physics. It arises from the fact that distance often plays an important part in the interaction of, or in determining the impact of forces on bodies. Moments are often described by their order [first, second…
