Question

An ant travels in a perfectly straight line in the

Answer 1

The ant starts moving along the negative x-axis, so its initial dispalcement is

Now it returns and moves 30 above the positive x-axis, so the displacement is

Final displacement of the ant is 40 below the positive x-axis. so the final dispalcement is

Since it reaches the initial point, thus the total dispalcement is zero.

     

and

Therefore, the magntiude of first displacement is 28.19 cm (or) 0.282 m

The magnitude of the second displacement is 19.28 cm (or) 0.2 m
