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 11) Chapter 2, Problem 6 Assume that Sean starts from rest and his motion...

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...

• HE'S BACK! In previous HW assignments (HW 10 and 14), we found that when we ignored the mass of the pulley, the man's speed was 11.35 ft/s when he hit the ground. Repeat the problem if the pulley is assumed to be a solid disk with a weight of 300 lb and a radius of 3 feet. Use work and energy.
