Question

What is the acceleration of the car whose speed increases uniformly from 15m/s to 25m/s in 5s?

Answer 1

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

Acceleration (a) = (Change in velocity) / Time

Given: Initial velocity (u) = 15 m/s Final velocity (v) = 25 m/s Time (t) = 5 seconds

Change in velocity = v - u

Substituting the given values into the formula, we get:

Acceleration (a) = (v - u) / t = (25 m/s - 15 m/s) / 5 s = 10 m/s / 5 s = 2 m/s²

Therefore, the acceleration of the car is 2 m/s².
