11. [-/4 Points] DETAILS SERPSET9 9.P.020. (a) What impulse did the athlete receive from the platform? N sup (b) With what speed did she reach the platform? m/s 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 63.0-kg athlete jumps down onto the platform from a height of 0.740 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 200t - 11 500t² where F is in newtons and t is in seconds. (c) With what speed did she leave it? m/s (d) To what height did she jump upon leaving the platform? m Additional Materials eBook MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER
