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.

This question is related to the concept of acceleration.

The correct answer is "(d) is increasing its velocity by 2.0 m/s every second".

The acceleration of an object is defined as the rate of change of its velocity over a given interval of time. Mathematically, acceleration is defined as the change in velocity of an object divided by the time interval taken for that change in velocity.

The Positive sign of the acceleration means the change in velocity is positive and the velocity is increasing, while the negative sign indicates a decrease in velocity.

Hence, an acceleration of 2 m/s² means that the velocity of the object is increasing by 2 m/s every second.

(d) is increasing its velocity by 2.0 m/s every second.

Explanation:

Acceleration is the change in velocity over time.

An acceleration of 2.0 m/s/s means the object's velocity is increasing 2.0 m/s per second.

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
