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.

Two bikers are cycling from the Greater Toronto Area to Kingston. The first biker, Merckx, started 200 kilometers (KMs) away from Kingston. The second, Froome started 20KM behind Merckx. Both cyclists start out slowly, but Merckx suffers a bike fault delaying them from starting for 11 hours and giving Froome a head start. Assuming the bikers match the below speed representing the maximum speeds of each biker from the time they begin moving, which biker will reach Kingston first and when? Which of the following answer is correct: a) Merckx in 36.2 hours b) Merckx in 31.2 hours c) Froome in 38.7 hours d) Froome in 35.6 hours

A runner, jogging along a straight-line path, starts at a position 60.0 m east of a milestone marker and heads west. After a short time interval he is 15.7 m west of the mile marker. Choose east to be the positive x-direction. What is the runner’s displacement from his starting point? Enter a positive value if the displacement is toward east of the milestone and a negative value if the displacement is toward west of the milestone.
