Question

In problem #5 what was George’s velocity in meters per second?

Answer 1

Your calculation of George's SPEED is correct.  Nice work !

Velocity is different.  Here's how to do velocity:

Velocity = (displacement) / (time)

Displacement = (distance and direction from start-point to end-point)

George ended 500 meters North of where he started.  So his displacement is 500 meters North.

Velocity = (500 meters North) / (13 seconds)

Velocity = 38.46 m/s North

Answer 2

Answer:

$v = 38.46 m/s$

Explanation:

As we know that velocity is defined as the ratio of total displacement of the object and total time taken by it

So here we know that

$v = \frac{d}{t}$

here we have

d = 750 (North) + 250 (South) m

$d = 750 - 250 m$

$d = 500$ m North

time taken by him is given as

$t = 13 s$

now we have

$v = \frac{500}{13}$

$v = 38.46 m/s$
