The saw will tip towards the heavy boy. they are centered on the main pivot point so weight dosnt matter but as they go out. mass and weight will determin if the saw moves or not
Answer: Force on the truck is equal to force on the car.
Explanation: According to the Newton's third law of motion which states that; For every action, there is an equal and opposite reaction. These pair of forces are regarded as action - reaction forces. These size or magnitude of the forces on the colliding objects are equal or the same, while the direction of the colliding objects are opposite.
In the scenario above, both truck and carry have the same mass, however, the damage suffered by the car is based on its smaller mass which makes it unable to withstand the acceleration resulting from the collision.
ma = m(-a)
m= mass, a= acceleration
