Ответ:
The magnitude and direction of the second force is -20 N in horizontal direction.
The given parameters;
mass of the block, m = 2 kgacceleration of the block, a = 5 m/s²one of the applied forces, F₁ = 30 N, at 0⁰The magnitude of the second force is calculated as follows;
Thus, the magnitude and direction of the second force is -20 N in horizontal direction.

Ответ:
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]
