A car moves behind a loaded truck, both moving with the same uniform velocity. A box falls from the top of the truck. If the driver of the car neither brakes nor accelerates, the car hits the box:
Options:
Answer:
B
Solution:
The box keeps the common horizontal velocity while falling, so relative to the car it falls straight down at a fixed horizontal distance ahead of the car. It therefore reaches the road first; the car meets it only after it has landed (and then, in practice, the box slows on the road while the car does not). Option B.
