Answer:
D = 3.0 m
Explanation:
- Assuming no other forces than gravity acting upon the criminal, his horizontal velocity must keep constant at 5.0 m/s.
- So, the horizontal displacement, applying the definition of average velocity, is just:
- In the vertical direction, the criminal is in free fall, starting from rest.
- Since we know the dfference in height between both roofs, we can use the kinematic equation for vertical displacement, as follows:
- Solving for t, we get:
- Replacing in (1), we get:
- So, if the horizontal distance between the two buildings is larger than 3.0 m, the criminal will fall to ground.
