if a person weighs 50kg and is simply standing still, the force of gravity is still acting on this person at an acceleration rate of 9.8m/s^2 find the force exerted by this person.
The force exerted by the person can be calculated using the formula:
Force = mass * acceleration
In this case, the mass of the person is 50 kg and the acceleration due to gravity is 9.8 m/s^2.
Force = 50 kg * 9.8 m/s^2
Force = 490 N
Therefore, the force exerted by the person when standing still is 490 N.
