Does it go like this? Dito's initial speed vi1 = 0 Dito's max speed vi2 = 70 km/h = 19,44 m/s (before the bungee engages, acceleration = 9,81 m/s²) The initial distance covered = the rope's lenght (h1) : (vi2)² = (vi1)² + 2gh1 (19,44)² = 0 + 2(9,81)(h1) h1 = (377,91)/19,62 h1 = 19,26 m Time to...

Is it possible that what the question means by "Dito's speed was 70 km/h when he fell" is the speed when he hit the water surface and the initial speed was zero? If we go by this assumption, the acceleration is definitely not 9,81 m/s². I think you're right and there is a problem with the...

Yep. 70 km/h. I also think that it is too fast, but that is what the question says.

70 km/h = (70.000 m/3600 s) = 19,44 m/s

vf²= vi² +2as vf² = (19,44)² + 2(9,81)(47) vf = 36,05 m/s to find the t, we can use formula: t = (vf - vi)/a t = (36,05 - 19,44)/9,81 t = 1,693 s. Is it correct?
