A car is travelling at constant velocity. Its brakes are then applied, causing uniform deceleration. Which graph shows the variation with distance s of the velocity v of the car?
AGraph A: velocity v decreasing non-linearly with distance s, concave down curve from max v at s=0 to v=0.
BGraph B: velocity v decreasing linearly with distance s from max v at s=0 to v=0.
CGraph C: velocity v decreasing non-linearly with distance s, concave up curve from max v at s=0 to v=0.
DGraph D: velocity v constant then drops to zero (step function).
