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

What is the velocity of the ball just after impact with the inclined wall, considering that the final velocity is purely horizontal?
Choices: 12.50 m/s to the left, 8.90 m/s, 33.9 m/s, 24.8 m/s
