Worksheet: Kinematics

In this worksheet, we will practice using the SUVAT equations to calculate the change in displacement and velocity of an object undergoing constant acceleration.


In 1967, New Zealander Burt Munro set the world record for an Indian motorcycle, on the Bonneville Salt Flats in Utah, of 295.38 km/h. The one-way course was 8.00 km long. He accelerated uniformly to reach 96.0 km/h from rest. If this time was 4.00 s and Burt accelerated at this rate until he reached his maximum speed, how long did it take Burt to complete the course?

Assume that downward displacement corresponds to positive values. Horizontal motion of the package is assumed to be negligible.
