You are driving a car on a country road when a mosquito splatters on the windshield. Which has the greater magnitude: the force that the car exerted on the mosquito or the force that the mosquito exerted on the car? Or are the magnitudes the same? If they are different, how can you reconcile this fact with Newton’s third law? If they are equal, why is the mosquito splattered while the car is undamaged?

an object travels for 5 minutes with constant motion. what conclusion can you make about the sum of the forces ( total force) acting upon an object? how did you reach this conclusion?

Question 3 and 4 are together

A 2100 kg truck has put its front bumper against the rear bumper of a 2400 kg SUV to give it a push. With the engine at full power and good tires on good pavement, the maximum forward force on the truck is 18,000 N. What is the maximum possible acceleration the truck can give the SUV? At this acceleration, what is the force of the SUV's bumper on the truck's bumper?

Which of the following are correct statements of Newton's 3rd law?  Choose all that are correct.   Any time an object feels a force (like gravity), it also feels a reaction force (like a table pushing up).     Any time an object exerts a force on a second object, that second object exerts an equal and opposite force on the first object.     The acceleration of an object is equal to the net force exerted on the object divided by its mass.     If an object is at rest, that means 2 equal and opposite forces are acting on it.

Which statement is most nearly the same as Newton's third law? A) If the net force acting on an object is zero, it does not accelerate. B) When you push on an object, it pushes back just as strongly on you. C) Acceleration of an object is proportional to net force divided by mass. D) When one object exerts a force on a second object, the first object exerts an equal force on itself in the opposite direction.

At the end of the day, Amy takes the elevator from her 32nd floor office down to the lobby of her building.  The elevator descends quite rapidly, and then slows down as it approaches the lobby level.  While the elevator is slowing down, compare the force of gravity on Amy to the force of the elevator floor on Amy.  Which is greater, or are they the same?  Explain how you know.

I am a little confused on Newtons Seconds Law in Two dimensions. I know that when acceleration is zero that the net force in both the x and y-directions becomes zero. Is that because when acceleration is zero there's no net force?
