Final answer:
When a vehicle is driven into a curve, it tends to decelerate due to the sideways force provided by friction between the tires and the road.
Step-by-step explanation:
When a vehicle is driven into a curve, it tends to decelerate. This is because the vehicle needs to change its direction, and in order to do so, it requires an inward force that acts towards the center of the curve. This force is provided by friction between the tires and the road, which opposes the vehicle's forward motion and causes it to slow down.
For example, when a car is rounding a bend at a constant speed, it experiences a sideways force due to the friction between its tires and the road, which causes it to decelerate. Similarly, a bowling ball rolling down a bowling alley also experiences a sideways force that slows it down as it moves towards the edge of the lane.
Therefore, the correct answer is b) Decelerate.
