141307 An athlete completes one round of a circular track of radius \(R\) in \(40 \mathrm{~s}\). What will be his displacement at the end of \(2 \mathrm{~min} 20 \mathrm{~s}\) ?

141308 A drunkard walking in a narrow lane takes 5 steps forward and 3 steps backward, followed again by 5 steps forward and 3 steps backward and so on. Each step is \(1 \mathrm{~m}\) long and requires 1 s. Determine how long the drunkard takes to fall in a pit \(13 \mathrm{~m}\) away from the starting point.
