Calculate Vertical Displacement in Stunt Jump | 2D Motion Physics Problem

[wwommack]

Homework Statement

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.
