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

A bird travels from island A to island B flying in a straight horizontal line. The distance between the two islands is 1 km. When there is no wind, the bird usually spends 2.50 kcal of energy for flapping its wings to create lift and move forward for the whole trip. Unfortunately, during the trip, a cold wind is present and induce a drag force on the bird of 35N, against the direction of motion. In addition, the temperature of...
