Starting from rest, a particle confined to move along a straight line is accelerated at a rate of 4 m/s 2 . -Which statement accurately describes the motion of the particle? A)The particle travels 4 meters during each second. B)The particle travels 4 meters during the first second only. C)The speed of the particle increases by 4 m/s during each second. D)The acceleration of the particle increases by 4 m/s² during each second. E)The final velocity of the particle will be proportional to the distance that the particle covers.

The statement "The speed of the particle increases by 4 m/s during each second" accurately describes the motion of the particle. This is because the particle is experiencing a constant acceleration of 4 m/s2, which means its speed increases by 4 m/s for every second of motion. Option A is incorrect because the distance the particle travels in each second will increase as its speed increases. Option B is incorrect because the particle's speed continues to increase after the first second. Option D is incorrect because the acceleration of the particle is constant, not increasing. Option E is incorrect because the final velocity of the particle depends on the time of motion and the acceleration, not the distance covered.
