Aroller-coaster car is traveling at a speed of 23 m/s when it passes through point b. at that point, it enters a concave down circular section of the track that has a radius of curvature of 60 m. after it reaches point b, the car’s speed increases at a rate of 4.75 m/s2. determine the time it takes for the car to reach point d.
