Final answer:
Joe is carrying a load with an approximate mass of 90 kg, calculated using the weight of 882 N (force) and the gravitational acceleration of 9.8 m/s².
Step-by-step explanation:
The question relates to the calculation of forces in a physics context, more specifically biomechanics, which is part of the physics curriculum. To calculate the mass of the load Joe is carrying, we use the gravitational force equation, which is the weight (W) divided by the acceleration due to gravity (g), where g is approximately 9.8 m/s². If Joe is carrying a weight of 882 in (which we interpret as a typo for Newtons, as inches are a unit of length, not weight), then the calculation for mass (m) would be:
m = W / g
m = 882 N / 9.8 m/s²
m ≈ 90 kg
So the mass Joe is likely carrying is approximately 90 kg. Incorrect lifting techniques, such as using the back instead of the legs, could lead to back injuries due to the large forces involved in lifting.
