A dragster going at 5 m/s north increases its velocity to 23 m/s north in 4 seconds. What is its acceleration during this time interval?

A dragster going at 5 m/s north increases
its velocity to 23 m/s north in 4 seconds. What is its acceleration during this
time interval? In order to calculate the acceleration of the boat we first have
to identify the suited formula for acceleration in this scenario. Hence, a = vf – vi / t. Vi = 5 m/s Vf = 23 m/s T =
4 seconds   Solution: A = 23 m/s – 5m/s / 4s A = 4.5m/s^2
