Answer:
Answer. Displacement = Distance between initial and final position. When he travels exact half of the circle then the distance between initial and final position is nothing but diameter of circle. Hence his displacement is 40 m
Answer:
Distance = 62.83m (approximately)
Displacement = 40m
Explanation:
Diameter = 40m
Radius = 40/2 = 20m
Circumference = 2*22/7*20 = 125.66m (app.) (Using formula)
Semi-circle = half of circumference = 125.66/2 = 62.83m (app.)
Distance travelled = Half of circumference = 62.83m
Displacement = Distance between the starting and ending point
So…
Displacement = Diameter (Diameter connects two ends of a semicircle formed)
Displacement = 40m
