A pendulum consisting of a small heavy ball of mass m at the end of a string at length L is released from a horizontal position. When the ball is at point P, the string forms an angle of 30 degrees with the horizontal.
a.) what are the forces acting on the ball and their directions...

A nonconducting sphere with center C and radius a has a spherically symmetric electric charge density. The total charge of the object is Q > 0.
a. Determine the magnitude and direction of the electric field at point P, which is a distance R > a to the right of the sphere's...
Homework Statement
A ball of mass M is thrown vertically upward with an initial speed Vo. It experiences a force of air resistance given by F=-kv, where k is a positive constant. The positive direction for all vector quantities is upward. Express all algebraic answers in terms of M, k, and...
