select all the correct answers. the net force on a car is zero in both the horizontal and vertical directions. which two situations could be true about the motion of the car? the car is speeding up onto the highway. the car is parked. the car is moving at a fixed speed and direction. the car is braking (slowing down). the car is being struck by another car.

select all the correct answers. the net force on a car is zero in both the horizontal and vertical directions. which two situations could be true about the motion of the car? the car is speeding up onto the highway. the car is parked. the car is moving at a fixed speed and direction. the car is braking (slowing down). the car is being struck by another car.

Answer

Answer:

B. The car is parked., C. The car is moving at a fixed speed and direction.

Explanation:

Step1: Recall Newton's first law

According to Newton's first - law, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. When the net force on an object is zero, it is either at rest or in uniform motion.

Step2: Analyze each option

  • Option A: When the car is speeding up onto the highway, there is a non - zero net force in the horizontal direction to cause the acceleration, so this is incorrect.
  • Option B: When the car is parked, it is at rest and the net force in both horizontal and vertical directions is zero. This is correct.
  • Option C: When the car is moving at a fixed speed and direction, it is in uniform motion and the net force is zero. This is correct.
  • Option D: When the car is braking (slowing down), there is a non - zero net force in the opposite direction of motion to cause the deceleration, so this is incorrect.
  • Option E: When the car is being struck by another car, there are unbalanced forces acting on it, so this is incorrect.
