Final answer:
The force of 25.0 N applied in the positive x-direction to the block will result in an acceleration of approximately 2.99 m/s² in the positive x-direction.
Step-by-step explanation:
The force of 25.0 N applied in the positive x-direction to a block of mass 8.35 kg will result in an acceleration of the block. To calculate the acceleration, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass:
acceleration = net force / mass
Plugging in the values, we have:
acceleration = 25.0 N / 8.35 kg ≈ 2.99 m/s²
Therefore, the block will accelerate at approximately 2.99 m/s² in the positive x-direction.
