Question

newtons first law of motion - 7.7d
a car sits still at a red light.
a car travels at a constant speed of 60 mph along a straight section of highway.
a driver switches lanes to prepare to exit.
a driver steps on the brakes to avoid a crash.

Explanation:

Step1: Recall Newton's First Law

Newton's First Law states that an object at rest or in uniform motion (constant velocity) has balanced forces, and the effect is no change in motion (or rest). For the scenario "A car sits still at a red light", the car is at rest.

Step2: Determine the effect of forces

Since the forces are balanced (from the table), and the car is at rest, the effect of the balanced forces is that the car remains at rest (no change in motion).

Answer:

No change in motion (the car remains at rest)
