In a scene in an action movie,a stunt man
jumps from the top of one building to the
top of another building 3.8 m away.After a
running start,he leaps at an angle of 18◦ with
respect to the flat roof while traveling at a
speed of 5.3 m/s.
The acceleration of gravity is 9.81 m/s2 .
To determine if he will make it to the other
roof,which is 2.3 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.
