    1. The problem statement, all variables and given/known data

    In a scene in an action movie, a stunt man
    jumps from the top of one building to the
    top of another building 4.8 m away. After a
    running start, he leaps at an angle of 11◦ with
    respect to the flat roof while traveling at a
    speed of 5.4 m/s.
    The acceleration of gravity is 9.81 m/s2 .
    To determine if he will make it to the other
    roof, which is 1.7 m shorter than the build-
    ing from which he jumps, find his vertical
    displacement upon reaching the front edge of
    the lower building with respect to the taller
    building. Answer in units of m.

    2. Relevant equations
    acceleration formula

    3. The attempt at a solution
    tried and got a crazy number
