Question

if a car accelerate at 5 m/s². what would be its final speed after 5.0 seconds if it’s starting speed were 10 m/s?

Answer 1

The final speed of the car after 5.0 seconds would be 35 m/s.

Step-by-step explanation:

To find the final speed of the car, we can use the formula:

Final speed = Initial speed + (Acceleration x Time)

In this case, the initial speed is 10 m/s, the acceleration is 5 m/s², and the time is 5.0 seconds:

Final speed = 10 m/s + (5 m/s² x 5.0 s) = 10 m/s + 25 m/s = 35 m/s

Therefore, the final speed of the car after 5.0 seconds would be 35 m/s.
