A player throws a ball with mass of 100 grams at an initial velocity v0 = 25 m/s with an angle θ = 60° from the horizontal at a height h1 = 1.5 m. The ball hits the wall inclined α = 45° from the horizontal, at point B with a height h2 = 2 m. After hitting the inclined wall, the ball rebounds horizontally to the left with a velocity v. Assume all surfaces are frictionless. Use angle of the velocity at point of impact β = 59.7°. Which of the following best approximates the magnitude of the velocity of the ball at point B just before impact with the inclined wall?  Choices: 12.50 m/s, 21.4 m/s, 25.0 m/s, 24.8m/s
