A car starts from 2.00 m/s and accelerates at 4.00 m/s2 for 6.0 s, it coasts for 5.00 s, and then slows down at a rate of 2.00 m/s2to a stop. How far has it traveled, in meters? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
2. A subway train starts from rest at a station and accelerates at a rate of 2.50 m/s2 for15.90 seconds. It then runs at a constant speed for 35 seconds and then slows down ata rate of 4.50 m/s2 until it stops at the next station.(a) What is the speed of the train just before it starts slowing down?(Ans.: = 39.75 m/s)(b) How long did it take the train to finish the trip from one station to the other?(Ans.: = 59.73 s)
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 Burt accelerated at this rate until he reached his maximum speed, a. how long did it take Burt to complete the course? b. Sketch position vs time, velocity vs. time, and acceleration vs. time graphs for the race.
