The picture above illustrates the horizontal forces acting on a car. The car's engine force pushes forward, while the friction between the tires and the road, along with the wind resistance drags the car in the backwards direction. Which of the following must be true about these forces if the car is driving forward on a level road at a constant speed of 45 mph?

• The force of the engine forward must be greater than the force of gravity acting on the car.

• The force of the engine forward must be greater than the combined forces of friction backward.

• The force of the engine forward must be less than the combined forces of friction backward.

• The force of the engine forward must be equal to the combined resistance forces.

As the roller coaster begins to descending a hill as shown in the diagam, your body feels like it is being pushed hard into the back of your seat. Which of the following is the correct explanation for this sensation?

• The roller coaster track applies a force on you that pushes you back into your seat as you go down the hill

• The force of gravity pulling you down makes you feel like you are being pushed into the back of your seat as the roller coaster accelerates down the hill

• As the roller coaster moves down the hill, it makes your body move with it and your body resists changing its motion which makes you feel like you're being forced into your seat.

• The roller coaster car you are in has more mass than you, so it moves faster down the hill, leaving you behind pressing you into your seat.
