    help me please!!!!!!!!!!!!

    1.a car drives straight off the edge of a cliff that is 55m high. the police at the scene of the accident note that the point of impact is 126m from the base of the cliff. how fast was the car traveling when it went over the cliff?

    I just need a hint of where to start?

    2.another question is about addition of vectors by means of components.
    I have the magnitude of three vecors
    a=5m north , b=17m east, and c=25m south east how do i solve for the line a+b+c?
