Explanation:
It is given that,
Mass of crate 1, [tex]m_1=2.8\times 10^2\ kg[/tex]
Mass of the crate 2, [tex]m_2=1.7\times 10^2\ kg[/tex]
It is also mentioned that the second crate is hanging below the first crate and attached to the first crate by a cable.
The acceleration of the helicopter, [tex]a=1.39\ m/s^2[/tex] (upwards)
The tension in the cable 1 is given by :
[tex]T_1=m_1(a+g)[/tex]
[tex]T_1=2.8\times 10^2(1.39+9.8)[/tex]
[tex]T_1=3133.2\ N[/tex]
The tension in the cable 2 is given by :
[tex]T_2=(m_1+m_2)(a+g)[/tex]
[tex]T_2=(2.8\times 10^2+1.7\times 10^2)\times (1.39+9.8)[/tex]
[tex]T_2=5035.5\ N[/tex]
Hence, this is the required solution.
