Answer:
The radius of the circle = r (i) When it completes half circle: - (Refer to Image 1)Distance = circumference2 = 2πr2 Distance = π r Displacement = r ...
Explanation:
Speed = distance travelled/time = half of the circumference/time = 1/2 × 2 × π × r/2 = 1/2 × 2 × 22/7 × 7/2 = 11ms1 Speed and velocity can be equal ...
