Question

embodied ravens along parts of radius 70m. after traveling half a revolution in 20 seconds. Find the (i) average velocity (ii) average speed.​

Answer 1

Answer:

Average speed = average velocity = 11m/s

Explanation:

avergae speed = total distnace / total time

given total time = 20s

total distance = 1/2×2π70 or π70

average speed = π70/20 or 3.5π or 3.5×22/7 = 0.5×22 = 11m/s

hope I'm correct
