## Calculate the weight of a boy of mass 110 kg.

Solution:

To calculate the weight of a boy with a mass of 110 kg, you need to multiply the mass by the acceleration due to gravity. On Earth, the approximate value for the acceleration due to gravity is about 9.8 m/s².

Weight = Mass × Acceleration due to gravity Weight = 110 kg × 9.8 m/s²

Weight ≈ 1078 kg·m/s² (which is equivalent to newtons, N)

So, the weight of the boy is approximately 1078 Newtons (N).
