Question

A rock at rest has weight 138 n. what is the weight of the rock when it is accelerating downward at 3.5 m/s2?

Answer 1

The weight of the rock when it is accelerating downward at 3.5 m/s² can be calculated using the formula Weight = Mass * Acceleration due to gravity.

Step-by-step explanation:

The weight of an object is equal to its mass multiplied by the acceleration due to gravity. In this case, the weight of the rock when it is at rest is 138 N. Since the rock is accelerating downward at 3.5 m/s², the weight can be calculated using the formula:

Weight = Mass × Acceleration due to gravity

Let's assume the mass of the rock is 'm'. The acceleration due to gravity is approximately 9.8 m/s² on Earth. So, when the rock is accelerating downward at 3.5 m/s², its weight can be calculated as:

Weight = m × 3.5 m/s²

Answer 2

The weight of the rock is 138n when accelerating downward at 3.5m/ s2.Weight is a measurement of the force of gravity on an objects mass. Therefore as long as the force of gravity is the same and the mass of the rock is the same the weight should also be the same.
