A car decelerates at −2.0 m/s2 and comes to a stop in 5 seconds. What was the original speed of the car in meters per second?
To find the original speed of the car, we can use the formula:
Where:
is the final velocity (0 m/s, since the car comes to a stop)
is the initial velocity (what we want to find)
is the acceleration ()
is the time (5 seconds)
Rearranging the formula to solve for :
