Question

A car requires 1500 meters of road in order to reach a good speed, of 80 m/s. What is the acceleration of the car that requires to reach the good speed and how much time will it take to reach it?

Answer 1

The acceleration of the car is 4.27 m/s² and it will take 18.75 seconds to reach a speed of 80 m/s.

Step-by-step explanation:

To find the acceleration of the car, we can use the equation:

acceleration = change in velocity / time taken

Since the car starts from rest, its initial velocity is 0 m/s. The final velocity is 80 m/s. The time taken to reach this velocity is 1500 meters / 80 m/s = 18.75 seconds.

Therefore, the acceleration of the car is 80 m/s / 18.75 s = 4.27 m/s².
