Final answer:
To recover from a skid on a slippery road, turn the wheels in the direction of the skid without slamming on the brakes or accelerating. The correct option is b. Turn the wheels in the direction of the skid.
Step-by-step explanation:
When your vehicle begins to skid on a slippery road, you should turn the wheels in the direction of the skid. This action is often referred to as "steering into the skid" and it allows the tires to realign with the direction of the vehicle and regain traction.
It is important to remain calm and to avoid slamming on the brakes or accelerating rapidly, as these actions can exacerbate the skid. Instead, gently steer in the direction you want to go and ease off the gas pedal or brakes until you feel the vehicle regain control.
Regarding the acceleration of objects, three ways an object can accelerate are by speeding up, slowing down, or changing direction. Acceleration is not limited to just increases in speed; it encompasses any change in velocity, which includes changes in both speed and direction.
Hence, b is the correct option.
