A v 2 u 2 2 s. This is because the reaction time is taken as a constant and distance speed time. How to Calculate Distance with Velocity and Time Given.
In physics you can calculate power based on force and speed.
A v 2 u 2 2 s. The force F required to move an object of mass m with an acceleration a is given by the formula F m x a. Acceleration equation for distance and velocity. D v x t.
