Calculate the average radius for Mercury's orbit. This can be done by averaging all the
radius vectors or more simply, by averaging
the longest and shortest radit that occur
along the major axis. The major axis is
shown in Figure 2. Recall that the sun is at
one focus; the other focus is located at a
point that is the same distance from the
center of the ellipse as the sun, but in the
opposite direction.

Atennis player used a tennis racket to hit a tennis ball with a mass of 0.25 kg with a force of 5.25 newtons. how does the force the tennis racket exerted on the tennis ball compare with the force the tennis ball exerted on the tennis racket? a. the force of the tennis racket on the tennis ball is equal in magnitude and opposite in direction to the force the tennis ball exerted on the tennis racket. b. the force of the tennis racket on the tennis ball is equal in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. c. the force of the tennis racket on the tennis ball is less in magnitude and in the same direction as the force the tennis ball exerted on the tennis racket. d. the force of the tennis racket on the tennis ball is greater in magnitude and opposite in direction as the force the tennis ball exerted on the tennis racket.
