a) A world record was set for the men's 100 m dash in the 2008 Olympic Games in Beijing by Usain Bolt of Jamaica. Bolt coasted across the finish line with a time of 9.69 s. If we assume that Bolt accelerated for 3.00 s to reach his maximum speed, and maintained that speed for the rest of the race, calculate his maximum speed and his acceleration. Umaz= a= b) During the same Olympics, Bolt also set the world record in the 200 m dash with a time of 19.30 s. Using the same assumptions as for the 100 m dash (that is, it took him 3.00 s to reach maximum speed), what was his maximum speed for this race?

When Sam drove at 9.5 m/s on university blvd, she passed her friend, Jess who was riding a bike at 5.0m/s. As Sam was passing Jess, she started to slow down while Jess kept her constant speed. So Jess caught up to Sam after 3 seconds. a.) Determine the distance traveled by Jess when she caught up to Sam.
Problem-Solving Technique: Draw a labeled picture. Put a coordinate system on the picture indicating the location of the origin and the positive direction. Show the solution in a step-by-step orderly fashion. Write any equation you use in symbolic form before substituting in numbers. 1. Ann is traveling at 30 m/s (80 mi/hr) west when she passes a police car. She immediately begins slowing down at a rate of 2.5 m/s for 4 seconds. How far has she traveled for this time? a. Fill in the information that is given in the problem. Put a question mark for any quantity that is not given in the problem. Vox = v. = b. Determine the distance she traveled in this time. Start with the equation in sy numbers you used including units. olic form and show the
NASA has fired a rocket straight up into the air from ground level with an unknown initial velocity. It reaches a maximum height of 164,000 feet. This happened in Cape Canaveral therefore the rocket is under the acceleration of Earth's gavity in which we all know is -32 ft/sec/sec. Please round your answers to two decimal places. a). Find the time it takes for the rocket to reach maximum height. b). find the initial velocity necessary to reach that height.
