As the jumper goes farther and farther down in each picture they are going farther and farther away from the bridge. Except for when they go back up then they are getting closer to the bridge. The bridge has no momentum while the jumper does which is why the bridge stays the same and the jumper is moving farther away due to his downward momentum.
Use v^2 - u^2 = 2as
Here, u = 20 m/s , a = -0.5 m/s^2 and v = 0
- 400 = -s ======> s = 400 m
Hope it helps, please mark me as brainliest and give me a good rating. Thank You!
