Challenge Problems
Push your limits with challenges.
Question 1
Given a leader vehicle that accelerates by 2 m/s² for 3 seconds, calculate the position of the leader at t = 3 seconds. If a following vehicle starts with a speed of 15 m/s and maintains a reaction time of 1 second, what speed will it be travelling at t = 3 seconds?
💡 Hint: First calculate the lead vehicle's position before determining the following vehicle's speed.
Question 2
Analyze the behavior of the following vehicle if the leader decelerates suddenly from 20 m/s to 10 m/s in 2 seconds. Calculate the new speed and position of the following vehicle assuming α = 10.
💡 Hint: Break the problem down into calculating the speed reduction and reaction time adjustments.
