5054Friction
A driver drives a car at uniform velocity along a road. The driver sees a hazard and applies the brakes. What is the car's motion as it moves through the thinking distance and as it moves through the braking distance?
- Amotion through the thinking distance: deceleration, motion through the braking distance: deceleration
- Bmotion through the thinking distance: deceleration, motion through the braking distance: uniform velocity
- Cmotion through the thinking distance: uniform velocity, motion through the braking distance: deceleration
- Dmotion through the thinking distance: uniform velocity, motion through the braking distance: uniform velocity
