- 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.arrow_forwardFor Number 8. please draw a diagram and do the math to explain the momentum For Number 9. please also do the math to show the relations between impulse and momentum Finally for 10, please show how momentum and impulse relate to the Force-time graph shown.arrow_forwardHow does the Impulse compare to the change in momentum?
