Given:
25 kg mass
Determine the force needed to a lift a 25 kg mass.
Solution:
In order to determine the force needed to lift a 25 kg mass, we will simply apply the apply the formula of force which is,
F = ma
F = Force
m = mass
a = acceleration
In a stationary body, even though it is not moving, there is a force of gravity that is applied, or the acceleration due to gravity, which caused any object to fall down. The acceleration due to gravity can be measured as,
g = 9.8 m/s^2
We can now solve the force needed by substituting the values on the given formula for force.
F = ma
F = (25 kg)(9.8m/s^2)
F = 245 kg . m/s^2
kg . m/s^2 is equal to N ( unit of Force)
Therefore, the force needed to lift a 25 kg object is 245 N.
