Answer :
Final answer:
The net force acting on the package as it slides down the ramp can be determined by calculating its weight, which is equal to its mass multiplied by the acceleration due to gravity. So, option d is the correct answer.
Explanation:
The net force acting on the package as it slides down the ramp can be determined using the concept of Newton's second law of motion. According to this law, the net force acting on an object is equal to the product of its mass and acceleration. In this case, since the package is sliding down the ramp, the net force can be calculated by multiplying the mass of the package by the acceleration due to gravity.
Therefore, the net force acting on the package is equal to its weight, which is the product of its mass and the acceleration due to gravity. The weight can be calculated using the formula: weight = mass × acceleration due to gravity. In this case, the weight of the package is equal to its mass multiplied by the acceleration due to gravity, which is approximately 9.8 m/s². So, the net force acting on the package is the weight of the package, which is given in the options.
Therefore, based on the given options, the correct answer is d) 152.5 N.
