Question

vv urgrnt Q6: A person completes a semicircular path of radius 7cm in 4 seconds. Calculate the the velocity of the body.        


​

Answer 1

Explanation:

distance = circumference/2 (since it's a semi-circular path)

distance = pi * r = 7pi cm

time = 4 seconds

distance = velocity * time

7pi = velocity * 4

velocity = 7pi /4 = 1.75pi cm/s

velocity = 0.0175 pi m/s
