An object is suspended from the ceiling using a piece of string. The string is attached through a spring scale with a reading of 45N.
What is the mass of the object hanging from the string?
m g = m(9.81) = 45
so
m = 45/9.81 kg
on earth
To find the mass of the object hanging from the string, we need to use the formula weight = mass * gravity.
In this case, the weight is given as 45N. The gravity on Earth is approximately 9.8 m/s^2. So, we can set up the equation as follows:
45N = mass * 9.8 m/s^2
Now, we can solve for the mass (m):
mass = 45N / 9.8 m/s^2
Dividing 45 by 9.8 gives us:
mass ≈ 4.59 kg
Therefore, the mass of the object hanging from the string is approximately 4.59 kg.
