Question

1. three factors that determine force of impact are

a. speed, weight, and distance between impact and stopping.
b. traction, brakes, and steering.
c. tire tread, visibility, and four - wheel drive.
d. shock absorbers, tire pressure, and roadway surface.

Explanation:

To determine the factors of impact force, we analyze each option:

• Option a: Speed (kinetic energy related to speed), weight (mass/force), and stopping distance (affects impact duration/force) align with physics principles of impact force ($F = \frac{\Delta p}{\Delta t}$, where momentum $\Delta p$ relates to mass/weight and velocity/speed, and $\Delta t$ relates to stopping distance).
• Option b: Traction, brakes, steering are vehicle control systems, not direct impact force determinants.
• Option c: Tire tread, visibility, 4 - wheel drive are vehicle/road conditions, not impact force factors.
• Option d: Shock absorbers, tire pressure, roadway surface are vehicle/road elements, not impact force determinants.

Answer:

a. speed, weight, and distance between impact and stopping.
