A test model for a new type of braking system is designed to apply a braking force that decays following an exponential function. For an object moving in the (+) x direction (to the right), the force acts in the opposite direction. When the brakes are applied, the velocity change as a function of time in seconds can be approximated by . v=v(t) = V, e-At where Vo is a constant in [m/sec) and A is a constant in [1/sec)....
