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.
Answer:
Explanation:
let the ladder is of mass "m" and standing at an angle with the ground
So here by horizontal force balance we will have
by vertical force balance we have
now by torque balance about contact point on ground we will have
so we will have
now from first equation we have
