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

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

    v_{0}=500, \;\ {\alpha}=30, \;\ g=9.8
