Quiz: Linear Kinetics 1. The force time curve below shows a person standing at rest. After the 1.5 seconds (not shown) the person completed a maximum vertical jump. Their total jump time was 1.4 seconds and their flight time was .65 seconds. The total jump impulse was 1350 N5. a. What is the person's impulse due to body weight? Ans: b. What is the person's net impulse? Ans: c. What is the person's vertical velocity at takeoff? Ans: 2. A person (m=50kg) traveling at 3 m/s not watching where he is going bumps into another person (m=65kg) traveling 2 m/s in the opposite direction and they travel together. They hit a padded wall and it takes 0.75 s to stop. a. What is their velocity immediately after the two people bump into each other? Ans: b. Assuming after the collision they travel with constant velocity, what is the average force the wall exerts on the two people? Ans
