A rocket is fired at an angle from the top of a tower of height ℎ0 = 50.0 m. Because of the design of the engines, its position coordinates are of the form () = +2 and () = +3, where , , , and are constants. Furthermore, the acceleration of the rocket 1.00 s after firing is if ⃗a = (4.00⃗i + 3.00⃗j) m/s2. Take the origin of coordinates to be at the base of the tower. (a) Find the constants , , , and , including their SI units. (b) At the instant after the rocket is fired, what are its acceleration vector and its velocity? (c) What are the - and -components of the rocket’s velocity 10.0 s after it is fired, and how fast is it moving? (d) What is the position vector of the rocket 10.0 s after it is fired?

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.
