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.

thanks in advance

You can use the general formulas for max height and range.

max height: $\displaystyle \frac{(v_{0}sin(\alpha))^{2}}{2g}$

Range: $\displaystyle \frac{(v_{0}^{2}sin(2\alpha))}{g}$

$\displaystyle v_{0}=500, \;\ {\alpha}=30, \;\ g=9.8$ - May 4th 2008, 07:36 AMsa87uk
