Standing on the top ledge of a 55 meter high building you throw a ball straight up with an initial speed of 29 m/s. How long, to the nearest second, does it take to hit the ground?(adsbygoogle = window.adsbygoogle || []).push({});

If the building in the previous question was 56 meters high and you throw the ball at 30 m/s, how high to the nearest meter does it go?

The correct answer to problem number one is 7

And number two is 102

Can't figure the formulas that need to be used in order to solve these..

Any help would be appreciated...
