Vector 2D Problem

  1. Sep 27, 2006 #1
    I would really appreciate it if you could help me out with this type of problem.....I'm struggling a bit on the order of work that I need to do.

    Problem: The ball is fired from the ground with an initial speed of 1.70 x 10^3 m/s at an initial angle of 55 degrees to the horizontal. Neglecting air resistance, find:

    a) The balls horizontal range?
    b) The amount of time the ball is in motion?

    My Thoughts: I'm not sure which formulas to begin with......I'm still slightly confused on the operations with component and vector projectile problems in 2D.

    This type of question is fundamntal. What equations of motion do you use for your foundation?

    This is a kinematics problem, not a vector problem.
