A projectile is fired from the ground (you can assume the initial height is the same as the ground) in a field so there are no obstacles in its way. It is fired at an angle of 24° with respect to the horizontal and with an initial speed of 25 m/s. Air resistance is negligible in this situation. Call up the positive y-direction, and toward the wall the positive x-direction.
What is the earliest time when the height of the projectile is half of its maximum value?
