Answer:
Open up the boxes so we can see the options
Step-by-step explanation:
J = m - 1 1/4 (ft).......j = m - 15 inches...because 1 1/4 ft = 15 inches
m = L + 1/3 (ft).......m = L + 4 inches....because 1/3 ft = 4 inches
L = 62 inches
m = L + 4
m = 62 + 4
m = 66 inches or 5.5 ft <==Maria
j = m - 15
j = 66 - 15
j = 51 inches or 4.25 ft <== Juan
Let angle HAC = A, then
cos A = 24/25 = 0.96
A = cos^-1(0.96) = 16.26
The answer is 161.70 N.
EXPLANATION
To change from mass to weight multiply by gravity (9.8 m/s^2)
Fw = m * 9.8 m/s^2
Fw = 16.5 kg * 9.8 m/s^2 = 161.70 N.
