A force platform is a tool used to analyze the performance of athletes measuring the vertical force that the athlete exerts on the ground as a function of time. Starting from rest, a $9.0-kg white jumps down onto the platform from a height of 0.670 m. While she is in contact with the platform during the time interval 0<t<0.800 s, the force she exerts on it is described by the function F-9 2006-11 500² where F is in newtons and t is in seconds. (a) What impulse did the athlete receive from the platform? 000.6 ✔N sup (b) with what speed did she reach the platform 3.6238 ✔m/s (c) with what speed did she leave a 3.13 x Your response differs from the correct answer by more than . Double check your calculations. m/s (d) To what height did she jump upon leaving the platform
