Option B: At 35 minutes the bicyclist was not moving.
Option C: From 6 to 12 minutes the bicyclist was increasing his speed.
Option D: From 24 to 30 minutes the bicyclist was traveling down a steep hill. Question 8 options:

Explanation:
It is given that,
Mass of a bungee jumper is 65 kg
The time period of the oscillation is 38 s, hitting a low point eight more times.It means its time period is
After many oscillations, he finally comes to rest 25.0 m below the level of the bridge.
For an oscillating object, the time period is given by :
k = spring stiffness constant
So,
When the cord is in air,
mg=kx
x = the extension in the cord
So, the unstretched length of the bungee cord is equal to 25 m - 5.6 m = 19.4 m
