Let’s neglect the effects of air resistance on the ball. The motion of the ball is animated in the simulation (linked below). The animation assumes that the ball’s initial location on the y axis is y0 = 1 m, and the ball's initial velocity has components v0x = 20 m/s and v0y = 20 m/s. What is the initial angle (in degrees) of the baseball's velocity? (Write only the numerical value of the answer and exclude the unit)A fly ball is hit to the outfield during a baseball game.
