Question

Physics: If a truck travels west with a constant velocity, the magnitude of the acceleration of the truck is:

A) 0 m/s²
B) 9.81 m/s²
C) 5 m/s²
D) 7 m/s²

Answer 1

For a truck moving with a constant velocity, the magnitude of the acceleration is 0 m/s², indicating no change in speed or direction.

Step-by-step explanation:

If a truck travels west with a constant velocity, the magnitude of the acceleration of the truck is 0 m/s². Velocity being constant indicates that there is no change in speed or direction, which is precisely the condition for zero acceleration. Acceleration is defined as the rate of change of velocity with time, and in this case, since the velocity is not changing, acceleration must be zero. This eliminates other given numerical options that represent a positive or negative acceleration value, as they suggest a change in velocity.
