A bowling ball is both sliding and spinning on a horizontal surface such that its rotational kinetic
energy equals its translational kinetic energy. What
is the ratio of the ball's center-of-mass speed to the
tangential speed of a point on its surface?

Two point charges are on the y axis. a 3.90-µc charge is located at y = 1.25 cm, and a -2.4-µc charge is located at y = −1.80 cm. (a) find the total electric potential at the origin. v (b) find the total electric potential at the point whose coordinates are (1.50 cm, 0). v
