You throw a ball toward a wall at speed 26.0 m/s and at angle ?0 = 38.0° above the horizontal. The wall is distance d = 21.0 m from the release point of the ball. (Consider up to be the positive y direction, and to the right to be the positive x direction.)
a) How far above the release point does the ball hit the wall?
b) What is the horizontal component of its velocity as it hits the wall? (Indicate the direction with the sign of your answer.)
c) What is the vertical component of its velocity as it hits the wall? (Indicate the direction with the sign of your answer.)
