    Question: A projectile is shot from the edge of a cliff 285 m above ground level, with an initial speed of vo=135 m/s and at an angle of 37.0 degrees with the horizontal, as shown in the attached figure. Please view attachment.

    a) Determine the time taken by the projectile to hit point P at ground level.
    b) Determine the range X of the projectile as measured from the base of the cliff.
    c) At the instant just before the projectile hits point P, find the horizontal and the vertical components of its velocity. (Assume the positive directions are upward and to the right.)
    d) What is the magnitude of the velocity?
    e) What is the angle made by the velocity vector with the horizontal?(below the horizontal)
