Investigators at a crash site observe that the skid marks are much longer and fainter than expected for the car's estimated speed. What is the most logical scientific conclusion?

The car's braking system must have applied an excessive amount of force.

The force of friction between the tires and the road surface was unusually low.

The car was significantly lighter than the average vehicle of its type.

The force of gravity must have been stronger at the specific location of the crash.

How does the force of friction relate to a car's rate of deceleration during a skid with locked wheels?

As friction decreases, the rate of deceleration increases.

Friction has no effect on the car's rate of deceleration.

As friction increases, the rate of deceleration increases.

Friction only determines if a skid happens, not the rate of deceleration.

A road covered in a thin layer of fine sand.

A recently rained-on asphalt surface.

A sheet of smooth, polished metal.

A dry, coarse-textured concrete road.

Car B will stop in a shorter distance than Car A.

Car B will leave skid marks that are longer and fainter than Car A's.

Car B will leave no skid marks at all because ice prevents friction.

Car B will have identical skid marks to Car A because their mass is the same.
