Answer:
We could reduce the force or increase the mass of the object.
Explanation:
Using the definition of force, according to Newton's second law, (F = ma) the acceleration is directly proportional to the force and inversely proportional to the mass. Therefore, if we want to reduce the acceleration of an object we have two options:
- We could reduce the force
- We could increase the mass
In both cases a will decrease.

<span>If an object is moving, the amount of kinetic energy it has directly depends upon which of the following factors?</span>
- the object's mass
- the object's velocity
The resultant vector is zero.
Explanation:
When you add displacement vectors using the head to tail method, you follow this procedure:
- Draw the first vector
- Draw the second vector, with its tail starting from the head of the first vector
- Draw the third vector, with its tail starting from the head of the second vector
.. and so on.
The resultant of the all vectors will be the vector connecting the tail of the 1st vector to the head of the last vector.
In this problem, the vectors make a closed polygon: this means that the head of the last vector coincides with the tail of the first vector.
Therefore, this means that the length of the resultant vector is zero.
