Question

A bungee jumper jumps from Bloukrans Bridge (South Africa), the highest commercial natural bungee jump in the world, at 216m. If a jumper is falling for 15 seconds, what is their rate of acceleration?

Answer 1

Explanation:

given

Heighr of fall S = 216m

Time taken t = 15seconds

Required

Acceleration

Using the equation of motion;

S = ut + 1/2at²

u = 0m/s

216 = 0 + 1/2a(15)²

216 = 225a/2

216 = 112.5a

a = 216/112.5

a = 1.92m/s²

Hence the rate of acceleration is 1.92m/s²
