A car has a velocity of 25m and accelerates uniformly to 45m/s in 10seconds.what is the acceleration?

change in velocity divided by time.

(45-25)/10

To find the acceleration, you need to use the following formula:

acceleration = (final velocity - initial velocity) / time

First, let's identify the given values:

The initial velocity (u) is 25 m/s (the car's velocity at the beginning)
The final velocity (v) is 45 m/s (the car's velocity at the end)
The time (t) is 10 seconds (the time it takes for the car to accelerate)

Now substitute the values into the formula:

acceleration = (45 m/s - 25 m/s) / 10 seconds

Simplifying this equation:

acceleration = 20 m/s / 10 seconds

The units cancel out, and you are left with:

acceleration = 2 m/s^2

Therefore, the acceleration of the car is 2 m/s^2.
