Answer:
The runner's acceleration as she sped up to the finish line is 0.95m/s²
Explanation:
Acceleration is the change in velocity of a body with respect to time. It is expressed as;
Acceleration = change in velocity/time
Change in velocity = final velocity - initial velocity
Acceleration = final velocity - initial velocity / time
Given initial speed = 8.0m/s
Final speed = 9.9m/s
Time taken = 2.0s
Acceleration = 9.9-8.0 / 2.0
Acceleration = 1.9/2
Acceleration = 0.95m/s²

I am pretty sure but not 100% that it would still continue to orbit
Average speed equal to = ,total distance traveled/total time taken
so it would be = 94+84/8
= 22.25 kmph
assume the east-west direction along the x-axis such that east lies in positive x-direction and west lie in negative Y-direction.
In unit-vector notation , individual displacement can be represented as
A = displacement of car in east direction = 60 i
B = displacement of car in west direction = - 90 i
D = total displacement of the car
Total displacement of the car is given as
D = A + B
inserting the values
D = 60 i + (- 90 i)
D = - 30 i
negative sign indicates the direction in west
hence net displacement is 30 km in west direction
