Oil drips at 0.4 second intervals from a car that has an oil leak. Which pattern best represents the spacing of oil drops as the car accelerates uniformly from rest?

Question

anonymous · Answer

Spacing between drops, dx, will be proportional to velocity dx=v dt , where dt is time between drops (0.4s). Velocity will increase as dv=a dt, with a the acceleration. Total distance will be 0.5 a t^2.
