2.25 m/s² of acceleration is required to increase the speed of a car from 26 mi/h to 51 mi/h in 5 seconds.
To find the answer, we need to know about the acceleration.
<h3>What is acceleration?</h3>
- Acceleration is given as the ratio of velocity to time.
- Mathematically, acceleration= velocity/time.
<h3>What is the acceleration required to increase the speed of a car from 26 mi/h to 51 mi/h in 5 seconds?</h3>
- Here change in velocity of the car is 51-26= 25 mi/h.
- As 1 mi/h = 0.45 m/s. So 25mi/h = 11.25 m/s.
- Acceleration= (11.25m/s)/5s = 2.25 m/s².
Thus, we can conclude that the constant acceleration is 2.25 m/s².

Answer:
Long question good luck:)..............
Explanation:
Answer:
The answer is A/B, they're the same answer anyways.
Explanation:
Chromatic aberration is the result when the lens fail to focus all the colors on the same point. The light then focuses in different points,and could lead to causing two images at once. The main culprit of this is usually dispersion.
Answer:10m/s
Explanation:
Wave speed ,v=for
Where π= wavelength=2m
Period =1/f f=frequency of wave
F=1/period
=1/0.2=5Hz
So speed of waves,v=5×2=10m/s
