An ant moves a rectangular path as shown in the figure. It starts A and moves with a uniform speed of 0.01 m s^(-1) , Determine the average speed after 1 hour.
Julian is recording the time take by an ant to travel on the edges of a wooden structure, shown in the given figure. He is amazed to observe that the ant takes exactly one second to travel the length of each edge. Distance covered in 3rd second is -
An ant is moving around a few food pieces of different shapes scattered on the floor.For which food-piece would the ant have to take a longer round? Remember,circumference of a circle can be obtained by using the expression c=2 pi r, where r is the radius of the circle.
