Question
A car is driving at a speed of 20 m/s when the driver sees a stop sign
up ahead. The driver puts her foot on the brake pedal. Which
statement accurately describes the forces acting on a car after the
driver hits the
brake pedal?
The forces are balanced because the acceleration and velocity of the car are
in opposite directions.
The forces are unbalanced because the car has a positive speed.
The forces are unbalanced because the velocity of the car is decreasing.
The forces are balanced because the car is moving at a constant speed.
