Homework Help: Shooting over a Hill

  1. Aug 31, 2006 #1
    A projectile is fired with speed v_0 at an angle
    Find the highest point in the trajectory,H .
    Express the highest point in terms of the magnitude of the acceleration due to gravity g, the initial velocity v_0, and the angle .
    What is the range of the projectile,R ?
    Express the range in terms of v_0,angle , and g.
    Find the angle above the horizontal at which the projectile should be fired.
    What is the initial speed?
    Find t_g , the flight time of the projectile

    Show some of ur own workings first. Like what Saketh have suggested. use the kinematics eqns to solve ur problem. These qns are quite straightforward.

    Decompose the velocity as x and y components first.
    the X and Y components are independent to each other
