Question

if a body can have zero average velocity but not zero average speed

Answer 1

Average speed is the ratio of total distance by TOTAL time taken. As average velocity depends on displacement and displacement can be zero if the object returns to initial position . ... Whereas displacement is zero as source and destination is same. Hence A body can have zero average velocity but not zero average speed.
