5) A soccer player kicks a ball, while imparting spin to bend it. The ball starts on the ground and is kicked with an initial velocity of 20 m/s, at an angle of elevation 45 degrees. Assume the ball was kicked east (positive x direction) and the spin creates a constant acceleration a to the north (positive y direction), making the ball follow a curved path. If the ball lands directly northeast of its starting point (45 degrees to both positive x and positive y, along the line y=x): a. What is the value of a? b. How long is the ball in the air? c. How far from the starting point does it land? Assume the standard value of g = 9.8 m/s².
