Homework Help: Projectile motion radar antenna

  1. Oct 26, 2008 #1
    1. The problem statement, all variables and given/known data

    A radar antenna is tracking a satellite orbiting the earth. At a certain time, the radar screen shows the satellite to be 162 km away. The radar antenna is pointing upward at an angle of 62.3 degrees from the ground. Find the x and y component(in km) of the position of the satellite.

    2. Relevant equations

    Vx=dx/t .................. a=Vy-V0y/t ............ Vy+V0y/2 = dy/t

    3. The attempt at a solution

    its a simple question but im thinking too hard

    V0y=Vo (cos) angle
    Vx= Vo(cos) angle

    Its just working out the lengths of two sides of a right angled triangle given the hypotenuse and angle. Draw a diagram of the situation and it will probably be a bit clearer.
