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

(A) 10𝑚/𝑠, 10𝑚/𝑠

(B) 10 𝑚/𝑠,0

(D) 0,10 𝑚/s

Answer : option (A)

Solution :

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