Answer:
The correct answer is;
3450 N
Step-by-step explanation:
The given parameters are;
The mass of the block = 345 kg
The location of the block = Earth
The weight, W, of an object on Earth is given by the mass of the object × The acceleration due to gravity
The acceleration due to gravity on Earth ≈ 10 m/s²
Therefore, we have;
The weight of the block on Earth = The mass of the block × The acceleration due to gravity of the block = 345 kg × 10 m/s²
∴ The weight of the block on Earth = 3450 kg·m/s² = 3450 N
A 350 kg block has a weight of 3450 N
(Therefore, a 34.5 kg block has a weight of 345 N)
