Answer:
I. The acceleration could be positive.
II. The acceleration could be zero.
III. The acceleration could be negative.
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
If the velocity of an object is zero at one instant, then the acceleration of that object may have the following characteristics;
I. The acceleration could be positive.
II. The acceleration could be zero.
III. The acceleration could be negative.
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Mathematically, acceleration is given by the equation;
Where,
a is acceleration measured in
v and u is final and initial velocity respectively, measured in
t is time measured in seconds.
