Answer:
speed = 11 m/s ; velocity = 7 m/s
Explanation:
radius of circular path , r = 7 m
calculating speed :
car cover half the distance of circular path in 2 s
distance = pie * r = 22/7 *7 = 22 m
speed = distance/time = 22/2 = 11 m/s
calculating velocity :
displacement cover by object in 2 s is equal to its diameter because the displacement is a vector quantity which have magnitude as well as direction
so, displacement = 14 m
velocity = displacement/time = 14/2 = 7 m/s
