- A force platform sensor used to measure the force of impact a 65.0 kg person makes with it after jumping down from a height of 0.600 m. During the contact time of 0 to 0.800 s, the platform records an average force on it of -1226.67 N. What impulse did the person receive from the platform? What was the velocity of the person right before they hit the platform? Neglect air resistance. What was the velocity of the person right after they left the platform? What was the average net force acting on the person? Using your answer from (d), determine the average contact force acting on the person.An estimated force-time curve for a baseball struck by a bat is shown in the figure below.
