a car starting from rest accelerates at a rate of 8.0 m/s. what is its final speed at the end of 4.0 seconds?I got 32m/s, is this correct
your of acceleration should be 8 m/s^2
your answer is correct
feel silly asking this, but how do u come up with 8m/s^2?
Youre not correct jk
To find the final speed of a car that starts from rest and experiences constant acceleration, you can use the equation:
final speed = initial speed + (acceleration * time)
In this case, the initial speed is 0 m/s (as the car starts from rest), the acceleration is 8.0 m/s², and the time is 4.0 seconds.
Plugging the values into the equation:
final speed = 0 m/s + (8.0 m/s² * 4.0 s)
final speed = 0 m/s + 32 m/s
final speed = 32 m/s
So, your answer of 32 m/s is indeed correct.
