Homework Help: Physics

Posted by Lindsay on Tuesday, September 25, 2007 at 6:17pm.

A robot probe drops a camera off the rim of a 239 m high cliff on Mars, where the free-fall acceleration is -3.7 m/s^2.
a) Find the velocity with which the camera hits the ground.
b) Find the time required for it to hit the ground.

Ok so I'm not even sure of which equation to use for this problem. Maybe if someone just gave me a hint as to where to begin, I could get the rest...?
