If you are an expert in the forensic science, what would you tell to the policemen? (Did he do it to himself?) .I m in front of a tall building. The dead

Explanation / Answer

1] Usint the relative motion concept, Vrel = 5 m/s, s = 30 m, a = -0.16 m/s^2

using second equation of motion,

30 = 5t +. 0.5*-0.16 t^2

time t = 6.723 s answer

distance x = vt = 33.6 m answer
