Answer:
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
[tex]v_{avg}=\dfrac{D}{T}[/tex]
Where, D = total distance
T = total time
Put the value into the formula
[tex]v_{avg}=\dfrac{20}{10}[/tex]
[tex]v_{avg}=2\ m/s[/tex]
We need to calculate the acceleration for the entire trip
Using equation of motion
[tex]v=u+at[/tex]
[tex]2=0+a\times10[/tex]
[tex]a=\dfrac{2}{10}[/tex]
[tex]a=0.2\ m/s^2[/tex]
Hence, The average speed of her is 2 m/s.
The acceleration for the entire trip is 0.2 m/s²
