Answer:
We conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.
Hence, option D is correct.
Explanation:
Given
- Force F = 500 N
- Acceleration a = 75 m/s²
To determine
Mass m = ?
Important Tip:
- The mass of a rock can be found using the formula F = ma
Using the formula
where
- F is the force (N)
- m is the mass (kg)
- a is the acceleration (m/s²)
now substituting F = 500, and a = 75 m/s² in the formula
switch sides
Divide both sides by 75
simplify
kg
Therefore, we conclude that the mass of a rock with a force of 500 N and an acceleration of 75 m/s² is 6.7 kg.
Hence, option D is correct.
