What force is necessary for a person to hold a 50 kg mass over their head?
F= m*g
5.1
To determine the force necessary for a person to hold a 50 kg mass over their head, we need to consider the effect of gravity on the mass. The force required is equal to the weight of the mass.
1. Calculate the weight (W) of the mass using the formula: W = m * g, where m is the mass and g is the acceleration due to gravity (approximately 9.8 m/s^2).
W = 50 kg * 9.8 m/s^2
W = 490 N
Therefore, a force of 490 Newtons would be necessary for a person to hold a 50 kg mass over their head.
To determine the force necessary for a person to hold a 50 kg mass over their head, we need to consider the effects of gravity.
The force required to hold an object against gravity is called the weight of the object, and it can be calculated using the equation:
Weight = mass * acceleration due to gravity
The acceleration due to gravity on Earth is approximately 9.8 m/s². So, the weight of a 50 kg mass would be:
Weight = 50 kg * 9.8 m/s²
Weight = 490 N
Therefore, the force necessary for a person to hold a 50 kg mass over their head would be approximately 490 Newtons.
