Point of correction, spring constant is 2.3×10−2 m not 2.3×10−2 m m
Answer:
28577 N/m
Explanation:
From Hooke's law, F=kx where F is force applied, k is spring constant and x is compression
F=mg=67*9.81
Approximately, 28577 N/m
The mass and tension due to the system are as follows:
- The mass of the child and scale = 10.6 kg
- The tension T, in the cord attaching the child to the scale = 104N
- The tension T', in the cord attaching the scale to the ceiling T' = 108.9 N
Tension is a type of pulling force due transmitted by means of a string or cable.
<h3>Force = mass * acceleration due to gravity</h3>a) The mass of the child and scale = 104/9.81 = 10.6 kg
b) The tension T, in the cord attaching the child to the scale = scale reading = 104N
c) The tension T', in the cord attaching the scale to the ceiling = scale reading + weight of scale
T' = 104 + (0.5 * 9.81)
T' = 108.9 N
d) The sketch is attached in the picture
In conclusion, the tension is force exerted on the cord due to the weight of the scale and the baby.
