Problem

A car moves around a circular track of radius

50\,\text{m}

at a constant speed of

10\,\text{m/s}

for

40\,\text{s}

. Answer the following: (i) Define uniform circular motion. (ii) Draw a clearly labeled speed–time graph for the entire

40\,\text{s}

interval. (iii) Explain, with reference to the definition you have stated, why the graph you have drawn is appropriate for the given motion.
