Q: Bob is a Formula 1 fan, lucky enough to obtain tickets for the last race of the season, and the tickets are excellent, facing the long straight part of the track, where most of the overtaking occurs. At one point during the race, the race leader reached the top speed of 300km/h, and he was almost in front of Bob when it happened. How fast was Bob's angle of vision changing when that happened? (In other words, find da/dt for the configuration in the picture)
