A baseball can be thrown from the outfield in two manners, one withno bounce at all and the other with a single bounce. Theorysays that the ball arrives sooner after the first bounce. The speed of the ball after the first bounce is one half the speed ofthe ball as the outfielders' throw which is 50m/s. Assume also that the angle at which it leaves the ground after the firstbounce is same as the angle at which it was thrown, 60 degrees.1- find the distance of the second bounce, if the fielder throwsthe ball to make it go the same distance with one bounce as a ball thrown upward at 45 degrees with no bounce.
2- Find the maximum height the ball reaches during the second bounce.
