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?

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
