Question

2 shonda is driving down the road. the force of gravity is pulling her car downward with 17,000 n, and the ground is pushing upward with 17,000 n. her car is producing a forward force of 880 n, and the air resistance is producing an 880 n force in the opposite direction. which statement accurately describes the motion of shondas car at this moment? the car is maintaining a constant speed, but turning the cars speed is decreasing the car is moving with constant velocity. the cars speed is increasing

Explanation:

Step1: Analyze vertical forces

The force of gravity \( F_g = 17000N \) (downward) and the normal force \( F_N=17000N \) (upward). Since \( F_g = F_N \), the net vertical force \( F_{net - vertical}=F_g - F_N=17000 - 17000=0N \).

Step2: Analyze horizontal forces

The driving force \( F_d = 880N \) (forward) and the air - resistance force \( F_{air}=880N \) (backward). The net horizontal force \( F_{net - horizontal}=F_d - F_{air}=880 - 880 = 0N \).

Step3: Determine motion using Newton's first law

According to Newton's first law, if \( F_{net}=F_{net - vertical}+F_{net - horizontal}=0 + 0=0N \), the object (car) will move with a constant velocity (either at rest or moving with a steady speed in a straight line). There is no information about turning (no unbalanced centripetal - like force mentioned). Since net force is zero, speed is not increasing or decreasing.

Answer:

The car is moving with constant velocity.
