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?

Step-by-step 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

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
