Question: At time t = 0 a small ball is projected from point A with a velocity of 200 ft/sec at the 60 angle. Neglect atmospheric

At time t = 0 a small ball is projected from point A with a velocity of 200 ft/sec at the 60° angle. Neglect atmospheric resistance and determine the two times t₁ and t₂ when the velocity of the ball makes an angle of 45° with the horizontal x-axis.
