Two forces are acting on a wheelbarrow. one force is pushing to the right and an equal force is pushing to the left. what can you say about the wheelbarrow's movement?
a) it is slowing down.
b) it is not accelerating.
c) it is moving faster and faster..
d) its speed is changing at a constant rate.

The correct option is (B) " It is not accelerating ".

Explanation :

It is given that two forces are acting on a wheelbarrow. One force is pushing to the right and an equal force is pushing to the left.

In this case, both the forces are equal and are acting in opposite direction. The net force acting on wheelbarrow cancels down and as a result, it will not move at all. This implies the forces acting on it is balanced.

Since, F = ma

It is clear that if the net force is zero, the object will not accelerate.

So, the reason behind the wheelbarrow's movement is (B) " It is not accelerating".
