Answer: 1 st law of motion
Step-by-step explanation:
Given
The bike hits the pothole and the driver flies over the handlebar. This can be explained by Newton's first law of motion. This law states that a body in the state of rest or motion will remain in that state unless an external force is applied to it.
Here, the bike instantly comes to rest by contacting the pothole which is at rest. while the driver body continues to move in forward direction and as a result it flies over the handlebars.
