A man can throw a ball a maximum horizontal
distance of 149 m.
The acceleration of gravity is 9.8 m/s2 .
How far can he throw the same ball verti
cally upward with the same initial speed?
Answer in units of m.

If you think about it, the total distance travled in the x direction is equal to the y direction since to get the max an object can go in the x direction is acquired at a 45 degree angle. So you are going a total of 149 m, at the highest point the distance traveled will be 149/2, because distance up always equals distance down. So the answer is 149/2 or 74.5 m.
