What force is necessary for a person to hold a 50 kg mass over their head?
ANSWER: WEIGHT
weight
To calculate the force necessary for a person to hold a 50 kg mass over their head, we need to consider the force of gravity acting on the mass. The force of gravity on an object can be calculated using the formula F = m * g, where F is the force, m is the mass, and g is the acceleration due to gravity.
In this case, the mass is 50 kg. The standard value for acceleration due to gravity on Earth is approximately 9.8 m/s^2.
So, to calculate the force required, we can use the formula:
F = m * g = 50 kg * 9.8 m/s^2
F = 490 Newtons
Therefore, to hold a 50 kg mass over their head, a person would need to exert a force of approximately 490 Newtons.
