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
To find the final speed of the car at the end of 4.0 seconds, we can use the formula:
Final Speed = Initial Speed + (Acceleration × Time)
Given that the car is starting from rest, the initial speed is 0 m/s. Also, the acceleration is given as 8.0 m/s², and the time is 4.0 seconds.
Plugging in these values into the formula, we get:
Final Speed = 0 + (8.0 × 4.0)
= 0 + 32.0
= 32.0 m/s
Therefore, the final speed of the car at the end of 4.0 seconds is 32.0 m/s.
