An 893kg dragster, starting from rest, attains a speed of 25 m/s in 0.59 seconds. What is the magnitude of the average net force on the dragster during this time?How to calculate magnitude of an average net force?
We can use Newtons second law of
Force = Mass x Acceleration.
As we are looking for the average force, we can model acceleration as a constant, so we have
Acceleration = Speed / Time.
Putting these together gives
Force = Mass x (Speed / Time)
= 893 x (25 / 0.59)
= 37838.98 N
