Question

A bungee jumper falls from a bridge 300 feet above ground. Her height above ground after t seconds is given by the equation h=16t^2+300 where h is the height of the jumper in feet and t is the time in seconds after she jumps. Approximately how long will it take for the bungee jumper to reach 100 feet above the ground on her initial jump?

Answer 1

I do not think so

I think h = 300 - 16 t^2
she is accelerating DOWN

100 = 300 - 16 t^2

t^2 = 200/16

t = 10 sqrt 2 / 4 = 2.5 sqrt 2
