Consider an aggressive car acceleration of a = 4.0 m/s2 and an initial car speed of v0 = 25 mi/h as the car enters the entrance ramp of a freeway where other cars are moving at 55 mi/h. (a} If the ramp has a length of d = 40 yd. what is the car's speed v in miles per hour as it attempts to merge? {b} What is the minimum length din yards needed for the car's speed to match the speed ofthe other cars?
