You are sitting in your car at a traffic light at the foot of a 200 ft long ramp that will take you onto the interstate. If your cat can at best accelerate at 5 m/s^2 and the traffic on the interstate is moving at 65mph. will the ramp be long enough for you to reach that speed and thus safely merge with the traffic?
would I use delta d=(v^2 - v_0^2)/(2a)
so thus the answer would be no the car would not safely merge with the traffic. Is this correct? Thanks in advance for your help.
