Two cars are driving on a road parallel to each other in the same direction. The trajectories of the cars are ξ = 1.5 m apart. Nicolas is d = 3 m away from the trajectory of the first car, which is moving at v₁ = 55 km·h⁻¹. What is the velocity of the second car if it always stays hidden behind the first car from Nicolas's point of view? We approximate the cars as point masses.
Nicolas waited for far too long at the bus stop.
