Chapter 2, Problem 39PE
In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, with a maximum speed of 183.58 mi/h. The one-way course was 5.00 mi long. Acceleration rates are often described by the time it takes to reach 60.0 mi/h from rest. If this time was 4.00 s, and BL11t accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course?

One simple model for a person running the 100 mm 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 11.1 m/sm/s in 2.44 ss , what will be his total time?

- An object is thrown from a level field with initial upward speed 17 m/s and forward speed 9.9 m/s. How far (in m) from its launch point is its landing place? You do not need to put the unit in the answer, just the number. As usual, ignore air resistance, etc; use the acceleration due to gravity as 9.8 meters per second squared.arrow_forwardAt a football tryout, a player runs a 40-yard dash in t2 = 5.00 seconds.
