Motion in two dimension help please

  1. Dec 19, 2011 #1
    A projectile is shot horizontally at 220 m/s from the top of a 620 m high cliff.

    A) How long till the projectile hits the ground?

    B) How far from the base of the cliff does the projectile land?

    I am gonna be honest. I have no idea how to do any of my Physics homework. ): I still have 3 more questions to do too outta 5.

    Welcome to the PF.

    Per the PF rules (see the Rules link at the top of the page), you need to show some effort on your schoolwork before we can be of tutorial help.

    What are the relevant equations for these types of problems? They are listed in your textbook or other learning materials. The equations relate the position, velocity and acceleration of the object versus time. Can you write those general equations here? And then how would they apply to these questions?
