in this answer the value is not seen so please you can put your value yourself

Explanation:

From FBD,

F=mgsinθ+f

or F=mg

x

h

+f as(sinθ=

x

h

)

or Fx=mgh+fx

or W

F

=mgh+W

f

as work done = force × distance.

150=5×10×2+W

f

or W

f

=150−100=

Explanation:

we get a horizontal components of

60 \sin(15)

before finding workdone we have to find force and acceleration

{v}^{2}   =  {u}^{2}  + 2as \\ 0 =  {10}^{2} + 2 \times a \times 25 \\  \\ a =  - 2m {s}^{2}

and therefore

f = ma \\ 6 \times  - 2 \\ 12n \: backwrd

w \:  = f \times d \\ (12 +  \ \: 60sin(15) ) \times 25 \\ 339.01j
