A car runs at a constant speed on a circular track of radius 100 ~m , taking 62.8 seconds for every circular lap. The average velocity and average speed for each circular lap respectively is:

Step-by-step solution

Distance trevelled in one revolution aligned & =2 r & Average speed = Totaldistance Total time & 2 r t = 2 3.14 100 62.8 & =10 ~m / s aligned Displacement in one revolution is zero. aligned Average Velocity = & Net displacement True & = 0 t =0 aligned
