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?
1.the car is speeding up onto the highway.
2.the car is parked.
3.the car is moving at a fixed speed and direction.
4.the car is braking (slowing down).
5.the car is being struck by another car.

Option 2 and 3

Explanation:

When the net force on the car is zero, the acceleration is also zero.

Along horizontal direction, the net force is zero. It means the car is moving with fixed speed and same direction.

Along vertical direction, the weight of the car is balanced by the normal reaction.

When the car is parked, the weight of the car is balanced by the normal reaction.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
