Answer:
Furthermore, the AEC said that the Joint Committee has made its position clear that it would no longer authorize any such subsidies. Yet, Mr. Chairman, we find.
After 5 seconds, the person would have travel 75 m
<h3>What is acceleration? </h3>
This is defined as the rate of change of velocity which time. It is expressed as
a = (v – u) / t
Where
- a is the acceleration
- v is the final velocity
- u is the initial velocity
- t is the time
<h3>How to determine the final velocity</h3>
We'll begin by obtaining the final velocity of the person. This can be obtained as follow:
- Initial velocity (u) = 10 m/s
- Acceleration (a) = 2 m/s²
- Time (t) = 5 s
- Final velocity (v) = ?
a = (v – u) / t
2 = (v – 10) / 5
Cross multiply
v – 10 = 2 × 5
v – 10 = 10
Collect like terms
v = 10 + 10
v = 20 m/s
<h3>How to determine the distance travelled</h3>
The distance travelled can be obtained as follow:
- Initial velocity (u) = 10 m/s
- Final velocity (v) = 20 m/s
- Acceleration (a) = 2 m/s²
- Distance (s) = ?
v² = u² + 2as
Collect like terms
2as = v² - u²
Divide both sides by 2a
s = (v² - u²) / 2a
s = (20² - 10²) / (2 × 2)
s = 75 m
Thus, the distance travelled by the person is 75 m

Answer:
The time taken to complete her run is 1.9 hr.
Explanation:
Speed is a scalar quantity and it is defined as the ratio of distance covered to the time taken to cover that distance. As distance is also a scalar quantity, so the directions given in the problem can be ignored. Thus, the distance covered by the jogger is the sum of kilometers given in problem.
Distance covered = 6+5+4 = 15 km
And the speed is given as 8 km/hr.
So the time taken will be ratio of distance to speed.
So the jogger will take 1.9 hr to complete her run.
