# A car starting from rest accelerates at a rate of 8.0 m/s. What is its final speed at the end at 4.0 seconds?

I hope it's helpful :D.

To find the final speed of the car, you can use the equation:

Final speed = Initial speed + (Acceleration * Time)

Given: Initial speed (starting from rest) = 0 m/s Acceleration = 8.0 m/s^2 Time = 4.0 seconds

Plug in the values:

Final speed = 0 + (8.0 * 4.0) = 32.0 m/s

So, the final speed of the car at the end of 4.0 seconds is 32.0 m/s.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
