A student investigates how the type of floor covering affects the average speed of a clockwork toy.
The student has a clockwork toy, a stopwatch and five different strips of floor covering. Two markers are placed 1.0 m apart on a level floor. Each strip in turn is laid flat so that it covers the whole distance between the markers.
Describe how the student could use the markers and the stopwatch to find the average speed of the toy on one of the floor coverings.
