Final answer:
The subject of this question is Physics. A sharp right curve with a maximum speed of 40 km/h involves understanding the concept of centripetal force and tire friction.
Step-by-step explanation:
The subject of this question is Physics.
A sharp right curve with a maximum speed of 40 km/h involves understanding the concept of centripetal force. Centripetal force is required to keep an object moving in a curved path. In this case, the speed of 40 km/h is the maximum speed at which the vehicle can safely navigate the sharp right curve without skidding or losing control.
Tire friction plays a crucial role in enabling the vehicle to take the curve at higher speeds. The friction between the tires and the road surface provides the necessary centripetal force to keep the vehicle moving in the curve.
