A jogger moves from a position x =
15.0 m to a position of x = 6.00 m in
4.00 s. What was her average velocity?
(Unit = m/s)
Don't forget: velocities and displacements to
the right are +, to the left are -

Approximately .

Explanation:

The velocity of an object is the rate of change in its displacement.

If it took time for an object to move from position to , then its average velocity would be

.

In this case,

...

.

Note that in this case, since , the value of is negative.

Hi, your answer is not correct. this is a cumulative  

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
