Final answer:
To determine the mass of the object, you can use Newton's second law of motion, which states that force equals mass times acceleration (F = ma).
Step-by-step explanation:
To determine the mass of the object, you can use Newton's second law of motion, which states that force equals mass times acceleration (F = ma). In this case, the force is 758 Newtons and the acceleration is unknown. However, the question states that the object is being pushed on a horizontal surface, so we can assume that the acceleration is zero since there is no mention of the object moving. Therefore, the force is balanced by friction, which is equal to the force pushing the object. Thus, the mass of the object can be calculated by dividing the force by the acceleration which will result in a mass of approximately 4.4 kg.
