Consider two vectors a~ and b~ and their resultant a~ + b~ . the magnitudes of the vectors a~ and b~ are, respectively, 15 and 7.3 and they act at 86◦ to each other. a~ b~ a~ + b~ find the magnitude of the resultant vector a~ + b~ . 005 (part 2 of 2) 4.0 points find the angle between the direction of the resultant vector a + b and the direction of the vector a. answer in units of ◦ .

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.
