A projectile is fired with an intial speed of 113 m/s at an angle of 60 degrees above the horizonal from the top of a cliff 49.0 m high(adsbygoogle = window.adsbygoogle || []).push({});

a) time to reach the max height

b) max height above the base

c) total time in the air

d) horizonal range of the projectile

I used the formula t^2 = Vo*sin 60/g

t^2 = 113*sin60/9.80 = 9.98 seconds

And after that i am totally lost and can't find any real go examples in the book.

where can i go from here and what formulas can i used Still going over notes and reviewing the book.

I also drew a picture
