Problem
An escaping prisoner needed to jump from one rooftop to another one because it's just the thing escaping prisoners do. The first building, from which he jumped, is H = 16m tall and the second one is h=11.6m, the buildings are d=4m apart. The velocity of the prisoner at the moment of jump is v=3.8m·s−1 and he is jumping parallel to the surface. Determine the missing/redundant distance (using the -/+ signs) after the jump relative to the rooftop of the second building. Air resistance is negligible. Assume gravitational acceleration g = 9.81m·s−2.
