Question

A bullet is fired at an angle of 30° above the horizontal with a velocity of 500m/s.
a)find the range.
b)Solve the time of itsflight.
c)At what other qngle of elevation coyld this bullet be fired to give the same range as in(a).
What is the maximum height attained by the bullet?


(a,c) see the article on Trajectory in wikipedia
(b) the height h is
h(t) = (500 sin30°) t - 4.9t^2
so solve for t when h=0
