1. ## An Object Fired.........

An object is fired from the ground with a velocity of 500 m/s at 30 to the horizontal. Calculate
a) the horizontal range;
b) the greatest height it reaches;
c) the time taken to rise to the greatest height.

max height: $\frac{(v_{0}sin(\alpha))^{2}}{2g}$
Range: $\frac{(v_{0}^{2}sin(2\alpha))}{g}$
$v_{0}=500, \;\ {\alpha}=30, \;\ g=9.8$
