A car is traveling at a constant speed of 30 m/s on a highway. At the instant this car passes an entrance ramp, a second car enters the highway from the ramp. The second car starts from rest and has a constant acceleration. What acceleration must it maintain, so that the two cars meet for the first time at the next exit, which is 2.8 km away?
I have tried this problem many different ways and keep on coming up with .161 m/s^2. I made sure to convert the km to m, but the answer is still wrong!
If anyone can help me see what I am doing wrong, that would be great!
