An object moving i n the +x direction has 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

An acceleration of +2.0 m/s^2 in the +x direction means that the velocity of the object is increasing by 2.0 m/s every second. So, the correct choice is D. Choice A is incorrect because it implies a constant velocity, whereas the question mentions an acceleration. Choice B is incorrect because it only gives the current velocity, not the change in velocity. Choice C is incorrect because it implies a negative acceleration, whereas the question mentions a positive acceleration.
