Question
Consider the baby being weighed in Figure 4.25.
(a) What is the mass of the child and basket if a scale reading of 102 N is observed?
= kg
(b) What is the tension T in the cord attaching the child to the scale?
= N
(c) What is the tension T' in the cord attaching the scale to the ceiling, if the scale has a mass of 0.300 kg?
= N
(d) Draw a sketch of the situation indicating the system of interest used to solve each part. The masses of the cords are negligible.
(Do this on paper. Your instructor may ask you to turn in this work.)
Explanation / Answer
I think you can do the sketching part
I am solving the question
a)
Scale will read T
weight of whild w is balanced by tension T
W= T
m*g = T
m*9.8 =102
m=10.41 Kg
b)
T = W = scale raeding
=102 N
c)
Consider the free body disgram of scale
downwatd force are T and weight of scale. Upward force is T'
so
T' = T + weight of scale
= 102 + 0.3*9.8
=104.94 N
