To solve this problem, we can use the kinematic equations for uniformly accelerated motion. The car starts from rest, so the initial velocity . The acceleration is given as . We need to find the time it takes to travel a distance mile and the velocity at that distance.First, let's find the time using the equation: Since , the equation simplifies to: Solving for : Next, let's find the velocity at that distance using the equation: Since , the equation simplifies to: Substituting the values: Therefore, the correct answer is:(d)
