Question

Two cars A and B are moving on same track in opposite direction with velocity 90 kmb' and 54 kmh respectively. When separation between them becomes 225 m, driver of both the cars apply breaks producing uniform deceleration in car A while deceleration of car B increases linearly with time at the rate of 0.3 ms. Find the minimum acceleration of car A to avoid
collision.​
