11. (Motion in Two and Three Dimensions) You throw a ball toward a wall at speed 25.0 m/s and at angle 0g = 40.0° above the horizontal (as given in figure below). The wall has a distance d = 22.0 m from the release point of the ball. i How far above the release point does the ball hit the wall? ii What are the horizontal and vertical components of its velocity as it hits the wall? iii When it hits, has it passed the high- est point on its trajectory? Answer: i) 12 m ii) V = = 4.8 m/s iii) NO 19.5 m/s, Vy 11.
