Atrain traveling at vo = 20.0 m/s begins to brake by applying a velocity-dependent instantaneous acceleration m/s2 a(v) = - v u 21.0 m2/s4, v is the instantaneous velocity of the train, and u = 0.8 m/s. where a determine the distance d traveled by the train before it comes to a complete stop. a (v) (uu) du (u) dt (0 + и) du %3d (а) dt integrate both sides of this equation to obtain an expression for in terms of t make sure to use appropriate integration limits or boundary conditions. then set v0 and solve for the time it takes the train to stop follow a similar procedure to obtain an expression for distance as a function of time. the resulting integral is not elementary; use the quadratic formula or an ntegral table to evaluate the integral
