Consider a bungee jumper of mass 65 kg with a 9.00-m cord tied to his ankles. When stretched, this cord may be treated as a spring, of spring constant 150 N/m. Note that the jump-off point is at x=9.00 m, and the origin for the x-coordinate is at the point where the rubber cord becomes taut.
a) At what point does the jumper attain maximum speed?
0=(65kg)(9.81)+150x
x=-4.25
b)what is the maximum speed?
mv^2=kx^2
v=6.3
c)at what point does the jumper attain maximum acceleration?
d) what is the value of this maximum acceleration?
I do not know how to do part c and d.
