Rock Problem

  1. Dec 11, 2016 #1
    1. The problem statement, all variables and given/known data
    A rock is thrown off of a 32 m high building with a horizontal velocity of 5 m/s. What is the vertical velocity when it reaches 6 m from the ground? Use g = 10 m/s^2

    A) 11 m/s
    B) 120 m/s
    C) 23 m/s
    D) 520 m/s
    E) 16 m/s

    2. Relevant equations
    Kinematics I think

    3. The attempt at a solution
    I think it is 23 m/s but not sure

    Whelp, then maybe a 10-day vacation from the very helpful PF will adjust your attitude. We require that students show effort on their schoolwork here.

    He created a sockpuppet to try to get around his temp ban, so he's not coming back. Unbelievable bad attitude.
