Final answer:
To merge safely onto an interstate, you should stay to the right on the on-ramp and accelerate to match the speed of the traffic, indicating your intention to merge with your turn signal.
Step-by-step explanation:
When you enter an interstate on-ramp, stay to the right and accelerate to allow your car to merge with traffic. Acceleration is vital as it helps to match the speed of the vehicles on the interstate, allowing for a safe and smooth merge.
For example, if a car merges onto the freeway traffic on a 200-m-long ramp with an initial velocity of 10.0 m/s and it accelerates at 2.00 m/s², we can calculate how long it takes to travel up the ramp using the principles of physics.
Decelerating or stopping on an on-ramp can be dangerous and is not the recommended action unless traffic conditions require it. Always use your turn signal to indicate your intention to merge.
