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
