Question

PLEASE HELP!!!

Because of the forces acting on the cart, it will
A: Accelerate to the right
B: Accelerate to the left
C: Accelerate upwards
D: Not accelerate

Answer 1

B. Accelerate to the left

Step-by-step explanation:

We know that the direction of forces is along the direction of the resultant force. The net force operating on the body, along with the body's direction, is referred to as the resultant force on the body. When the object is at rest or moving at the same speed as the object, the resultant force is zero.

Let us consider the forces on the right side direction as positive and on the left side direction as negative.

From figure, the force along right direction is +50 N, the force along left direction is -150 N.

So we can write

`F_(right) =+50 N`

`F_(left) =-150 N`

The total or resultant force can be determined as

`F_(net) =F_(right) +F_(left) =+50-150=-100 N`

The direction of resultant force is negative, so force will be along left direction. Acceleration of the body is always along direction of force, so the body will accelerate to the left.
