the 1996 Olympic times for Michael Johnson in the 200 m and Donovan Bailey's 100 meter times are shown. Both athletes won their races and won a gold medal. Your task is to explain which athlete had the highest Maximum Instantaneous Velocity during their race. Support for your answer using information in the book, formulas and/or inductive reasoning based on your understanding of these races. You will not be able to calculate the exact maximum velocity, but the material presented...

Please answer all questions. 1. One simple model for a person running the 100 m dash is to assume the sprinter runs with constant acceleration until reaching top speed, then maintains that speed through the finish line. If a sprinter reaches his top speed of 11.4 m/s in 2.34 s , what will be his total time? 2. Excellent human jumpers can leap straight up to a height of 120 cm off the ground. To reach this height, with what...

6. Sean is running a 100 m dash. When the starter's pistol fires, he leaves the starting block and continues speeding up until 6 s into the race, when he reaches his top speed of 11 m/s. He holds this speed for 2 s; then his speed has slowed to 10 m/s by the time he crosses the finish line 11 s after he started the race. List of Equations (Use only if the problem must be solved in terms...

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...

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
(a) What is the force exerted to keep the car moving at constant
speed?
