What is the mass of a 1400-N object?

To find the mass of an object given its weight in newtons, you can use the formula: weight = mass x gravity. Rearranging the formula to solve for mass gives mass = weight / gravity. Since the weight is 1400 N and gravity is approximately 9.81 m/s^2, the mass of the object would be 1400 N / 9.81 m/s^2 ≈ 143 kg.
