A man can throw a ball a maximum horizontal(adsbygoogle = window.adsbygoogle || []).push({});

distance of 138 m.

The acceleration of gravity is 9.8 m/s2 .

How far can he throw the same ball vertically upward with the same initial speed?

Answer in units of m.

I figured out the initial speed to be about 280 m/s. Am I right? How can I finish the problem?
