7) The maximum horizontal distance a boy can throw a ball is 50.0 m. Assume he can throw with the same initial speed at all angles. How high does he throw the ball when he throws it straight upward?

Given: v is constant at any value and x=50 m, then find the maximum hieght which is . We can also see that the motion of horizontal direction is given by , and also, since it's , also . So now just put this in the equation you will get ymax being 12.6 along with using the equation .

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)
