    Why Is My Calculation of Coulomb's Force Incorrect?

    I thought this would be a basic physics problem, but I'm not getting the right answer, here's the problem: There are two identical small metal spheres with charges 27.5 μC and −19.119 μC. The distance between them is 8 cm. The spheres are placed in contact then set at their original...

    How Do You Calculate the Angle in a 2D Elastic Collision?

    Homework Statement Consider an elastic collision (ignoring friction and rotational motion). A queue ball initially moving at 2.9 m/s strikes a stationary eight ball of the same size and mass. After the collision, the queue ball’s final speed is 1 m/s. Find the queue ball’s angle with respect...
