Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?

The average time that it takes for the car to travel the first 0.25m is s. the average time to travel just between 0.25 m and 0.50 m is s. given the time taken to travel the second 0.25 m section, the velocity would be m/s.
