A car is initially traveling at 20 m/s when it accelerates to 35 m/s in a time of 5 seconds. What is the acceleration of the car in m/s^2?

a = (v -v(o))/t =(35 – 20)/5 =3 m/s^2.

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

acceleration = change in velocity / time

In this case, the change in velocity is the final velocity minus the initial velocity, and the time is given as 5 seconds.

So, the change in velocity is 35 m/s - 20 m/s = 15 m/s.

Now we can substitute these values into the equation:

acceleration = 15 m/s / 5 s = 3 m/s^2.

Therefore, the acceleration of the car is 3 m/s^2.
