A driverless car collides head on with a stationary sign. The collision brings the car to a stop, but does not move the sign.
Which design feature would have minimized the force of impact in the collision?
A. a car that can carry a greater mass of passengers and cargo
B. a sign that breaks loose from the ground when a force is applied to it
C. a sign that can withstand the force of a more massive car without moving
D. a car that can decelerate at a greater rate during collisions by not bending on impact
