What is tangential acceleration and its magnitude 12. if a projectile that was launched from the ground with an initial velocity 100 m/s in the direction 30° north of east collides a rocket that was fired due east 4s after the projectile reached its highest point, how high up was the rocket fired and with what velocity given that the rocket has a constant velocity and was fired when the projectile was over head? 13. a car has a constant acceleration of 0.300 m/s2 and a horizontal velocity of 8.00 m/s at the moment the care is at the top of the rise of the roadway that is shaped like a circle of radius 500 m. what is the magnitude and direction of the total acceleration vector for the car at this instant?

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.
