Homework Help: Question about vectors, velocity, time and distance?

  1. Feb 4, 2009 #1
    An arrow is fired at and angle of 45 degrees with a velocity of 30 m/s above the horizontal off the edge of a 3m high cliff.

    A) Resolve the initial velocity into its x and y components.
    B) Find how long it takes the arrow to hit the ground below the cliff
    C) Find how far from the cliff the arrow hits the ground.

    PLease give some hints/formulas or ways to show me how to solve this

    Have you been given any formulas you think might relate to this problem? What theory have you gone through?

    We have been doing forulas with stuff like j hat and i hat
    Equations with initial and final velocity, time, inital and final displacement and acceleration
