Problem

A velocity–time graph for a glider on an air track shows that its speed reaches a maximum value of

0.31\,\text{m}\,\text{s}^{-1}

, and the time between successive positive speed maxima is

1.2\,\text{s}

. What is the amplitude of the glider’s oscillation? a)

0.118\,\text{m}

0.059\,\text{m}

0.39\,\text{m}

0.035\,\text{m}
