Based on what you have learned about the laws of motion in this unit, you will work as an engineer to develop and present a new design proposal to the local school board to make school buses even safer for their passengers and other vehicles on the road. Your design proposal will need to include the following: An explanation of how each of Newton's Laws of Motion relate to a collision between a bus and a car o How will the bus be impacted based on its mass? o How will the car be impacted based on its mass? o How will the passenger in the car be impacted? o How will the passengers on the bus be impacted?
