Question

(6%) Problem 16: Consider the baby being weighed in the figure Randomized Variables f= 51 N m = 0.52 kg 33% Part (a) What is the mass (in kg) of the child and basket if a scale reading of 51 N is observed? sin0 tanO cosO cotanO asin0 acos0 atanO acotan)sinh(0 cosh0 tanh) cotanh0 Degrees Radians de 0 DEL CLEAR Submit Hint I give up! Hints: 30% deduction per hint. Hi ints remaining: 2 Feedback: 33% Part (b) What is the tension T1 in the cord attaching the baby to the scale? 33% Part (c) What is the tension T2 in the cord attaching the scale to the ceiling, if the scale has a mass of 0.52 kg?

Explanation / Answer


part(a)

weight of child = reading = 51 N = m*g


mass of child m = W/g = 51/9.8 = 5.2 kg


==================


part (b)

In equilibrium


along vertical Fnet = 0


T1 - W = 0

T1 = W = 51 N <<<<--------ANSWER


==============

part (c)


In equilibrium


along vertical Fnet = 0

T2 - T1 - Wscale = 0

T2 - T1 - Mscale*g = 0

T2 - 51 - (0.52*9.8) = 0

T2 = 56.1 N <<<_------------ANSWER
