The average speed of her is 2 m/s.

The acceleration for the entire trip is 0.2 m/s²

Explanation:

Given that,

katie measured the distance her friend morgan ran on a straight track every 2s.

According to given chart,

We need to calculate the average speed

Using formula of average speed

$v_{avg}=\dfrac{D}{T}$

Where, D = total distance

T = total time

Put the value into the formula

$v_{avg}=\dfrac{20}{10}$

$v_{avg}=2\ m/s$

We need to calculate the acceleration for the entire trip

Using equation of motion

v=u+at

$2=0+a\times10$

$a=\dfrac{2}{10}$

$a=0.2\ m/s^2$

Hence, The average speed of her is 2 m/s.

The acceleration for the entire trip is 0.2 m/s²
