JEE Main 2024 Physics question
Two cars are travelling towards each other at speed of 20 ms⁻¹ each. When the cars are 300 m apart, both the drivers apply brakes and the cars retard at the rate of 2 ms⁻². The distance between them when they come to rest is :
Answer: (C)
Solution
Use the relative motion: the initial relative speed is 40 m/s and the relative retardation is 4 m/s². The relative
