Answer #1

Let he covers a distance x along the west direction

He covered 6.44 km west at a speed of 2.5 m/s.

So, time required is

Now to traverse x km distance at 1.35 m/s, time required is

We will consider west as potive

So, average velocity is

A bicyclist rides 1.53 km due east, while the resistive force from the air has a magnitude of 8.77 N and points due west. The rider then turns around and rides 1.53 km due west, back to her starting point. The resistive force from the air on the return trip has a magnitude of 8.77 N and points due east. Find the work done by the resistive force during the round trip.
