Step-by-step explanation:
using the formula :
2.d.s = V²-Vo²
2(-0.15) (60) = V² - (8.55)²
-18 = V² - 73.1
V² = 73.1 - 18
V² = 55.1
=> V = √55.1 = 7.4
so, the velocity when she ends the race =
7.4 m/s
Answer:

Step-by-step explanation:
We must write the function of the line in the form 
First calculate the slope m



Then

To have b replaced a point in the function
