The correct answer is towards right (+x axis) .
In physics, velocity is characterized as a vector measurement of the motion's direction and speed. To be more precise, the rate of change in an object's location relative to a frame of reference and time is another way to describe velocity. The definition of velocity simply states the rate of motion of an item in a certain direction. It determines how quickly or slowly something is going.
Whether an item is moving faster or slower, acceleration is defined as the rate of change in velocity of that object. Acceleration is seen as good or negative depending on how quickly something is moving.
t1 = 0, v1 = 16.0 m/s
t2 = 4.0 s, v2 = 4.0 m/s
acceleration, a = (v2 - v1)/(t2 - t1)
= (4 - 16)/(4 - 0)
= -3.0 m/s^2
magnitude of acceleration, |a| = 3.0 m/s^2
direction : towards right (+x axis)
