Answer:
The direction is to the right. The magnitude is 10 newtons.
D is correct.
Explanation:
Given that,
Time t = 9 sec
Force F = 10 N
distance = 4 meter
According to given scenario
The object moves to the right direction due to the force.
So, The direction of force will be to the right.
Force is a vector quantity. It has both magnitude and direction.
The object is moving by 10 N force.
Therefore, The magnitude of the force would be 10 N.
