An object moving in the +x direction experiences an acceleration of +2.0 m/s².This means the object A)travels 2.0 m in every second. B)is traveling at 2.0 m/s. C)is decreasing its velocity by 2.0 m/s every second. D)is increasing its velocity by 2.0 m/s every second.

Question

Quizplus · Accepted Answer

The given acceleration is in the positive direction (+x direction) and has a positive value (+2.0 m/s^2), which means the object is accelerating in the positive direction at 2.0 m/s^2. Therefore, the object is increasing its velocity by 2.0 m/s every second. Option D is the correct answer. Option A is incorrect since the object's distance traveled cannot be determined from its acceleration alone. Option B is incorrect since the acceleration and velocity are not equal. Option C is incorrect since the acceleration is positive and not negative.
