A2 kg block is accelerating at the rate of 5 m/s² while being acted on by two forces. One of the forces equals 30 N, 0°. What are the
magnitude and the direction of the other force?

The magnitude and direction of the second force is -20 N in horizontal direction.

The given parameters;

The magnitude of the second force is calculated as follows;

Thus, the magnitude and direction of the second force is -20 N in horizontal direction.

20 [N], in the opposite direction of the first force.

Explanation:

We know that newton's second law stipulates that the sum of forces on a body must be equal to the product of mass by acceleration.

The negative sign means that the other force acting on the body must be in the opposite direction to the force of 30 [N]
