How much weight of a 50 kg boy who's pushing a 30 kg crate?
Well if your supposed to add them together then it would be 80kg
Your question makes no sense, try providing a more detailed question.
To calculate the total weight being exerted by the 50 kg boy when pushing the 30 kg crate, you need to add the weight of the boy to the weight of the crate. The weight of an object is the force exerted on it due to gravity, which can be calculated using the formula:
Weight = mass × acceleration due to gravity
The acceleration due to gravity is approximately 9.8 m/s².
To find the weight of the boy, we multiply his mass (50 kg) by the acceleration due to gravity (9.8 m/s²):
Weight of the boy = 50 kg × 9.8 m/s² = 490 N
To find the weight of the crate, we multiply its mass (30 kg) by the acceleration due to gravity (9.8 m/s²):
Weight of the crate = 30 kg × 9.8 m/s² = 294 N
Finally, to find the total weight being exerted, we add the weight of the boy to the weight of the crate:
Total weight = Weight of the boy + Weight of the crate = 490 N + 294 N = 784 N
Therefore, the total weight being exerted by the boy pushing the crate is 784 N.
