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.
