Review Careful measurements have been made of Olympic sprinters in the 100-meter dash. A quite realistic model is that the sprinter's velocity is given by Ua(1-e- where t is in s, Ux is in m/s, and the constants a and b are characteristic of the sprinter. Sprinter Carl Lewis's run at the 1987 World Championships is modeled with a - 11.81m/s and b- 0.68875 Part A What was Lewis's acceleration at t0s? Express your answer using four significant figures Submit...

1. Usian Bolt holds the 100 m world record with a time of 9.58 s. During the race, he has a reaction time of 0.15 s, and then he accelerates at a constant rate from rest to his top speed in 2.73 s. He then runs at this top speed for the rest of the race. a) What was his top speed during the race? Hint: You might find it helpful to start this problem by sketching the velocity vs...

Class worksheet: Kinematics in One Dimension Kinematic equations: Va, A 2 1. The Rogue River in Oregon is so rocky in spots that jet boats become a popular way for tourists to see wild stretches of the river. A system of air jets thrusting downward keep the boat suspended above the water and a second system of air jets move it horizontally. A jet boat driver comes around a bent in the river moving due west at a speed of...
