Suppose that you are viewing a soccer game from a helicopter above the playing field. two soccer players simultaneously kick a stationary soccer ball on the flat field; the soccer ball has mass 0.420 kg. the first player kicks with force 162 n at 9.0° north of west. at the same instant, the second player kicks with force 215 n at 15° east of south. find the acceleration of the ball in i ^ and j ^ form.

Two thin 80.0- cm rods are oriented at right angles to each other. each rod has one end at the origin of the coordinates, and one of them extends along the x- axis while the other extends along the yaxis. the rod along the x- axis carries a charge of - 15.0 μ c distributed uniformly along its length, and the other rod carries 15.0 μ c uniformly over its length. find the magnitude and direction of the net electrical force that these two rods exert on an electron located at the point (40.0 cm, 40.0 cm).

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.
