A car moving initially with velocity v₀ with deceleration a comes to a full stop after traveling a distance d. We can say that the velocity of the car after traveling a distance d/2 is A) greater than v₀/2. B) equal than v₀/2. C) smaller than v₀/2. D) has no relationship to v₀.

Question

Quizplus · Accepted Answer

Using the equation v^2 = v0^2 - 2ad, at d/2, the velocity is greater than v0/2 because the car has not yet traveled the full distance d to stop.

A Car Moving Initially with Velocity V0 with Deceleration a Comes

A Car Moving Initially with Velocity V₀ with Deceleration a Comes
