And and climb up 5 stairs , each of width 20 cm and height 20 cm . Find the distance covered and displacement of ant ?

To find the distance covered by the ant, we need to calculate the total length it travels while climbing all the stairs.

The width and height of each stair are given as 20 cm. Since the ant needs to cover both the width and height of each step, the total distance covered by the ant while climbing one stair is given by:

Distance covered per stair = 2 * (width + height) = 2 * (20 cm + 20 cm) = 2 * 40 cm = 80 cm

Since there are a total of 5 stairs, we can calculate the total distance covered by the ant by multiplying the distance covered per stair by the number of stairs:

Total distance covered = Distance covered per stair * Number of stairs = 80 cm * 5 = 400 cm

Therefore, the ant covers a distance of 400 cm while climbing the 5 stairs.

Now, let's calculate the displacement of the ant. Displacement is the shortest straight-line distance from the initial position to the final position.

Since the ant starts at the bottom of the stairs and climbs to the top, the vertical displacement is the height of the stairs, which is 20 cm.

The horizontal displacement is zero because the ant returns to the same location horizontally as before.

Therefore, the displacement of the ant is 20 cm vertically and 0 cm horizontally.
