Answer:
The value is
Explanation:
From the question we are told that
The force exerted by student 1 is [tex]\vec F_1 = F_0 \^ i[/tex]
The force exerted by student 2 is [tex]\vec F_2 = - 3 F_o \^ j[/tex]
The force exerted by student 3 is [tex]\vec F_3 = -4F_o \^ i + G \^ j[/tex]
The displacement of the T-shirt is [tex]\vec D = 2d\^ i + d\^ j[/tex]
Generally workdone is mathematically represented as
[tex]W = \vec F * \vec d[/tex]
Generally workdone is student 3 mathematically represented as
[tex]W_3 = \vec F_3 * \vec D[/tex]
=> [tex]W_3 = -4F_o \^ i + G \^ j * [2 d \^ i + d\vec j ][/tex]
=> [tex]W_3 = -8F_o d * Gd[/tex]
