Answer:
Work done is 1026.48 J.
Explanation:
Given :
Mass of both sister and sled , m = 34 kg.
Angle from ground of force, [tex]\theta=33^o[/tex].
Force applied , F = 26 N.
Distance travelled , d = 47 m.
We know, work done is, W = F.d = [tex]Fdcos\theta[/tex] ( [tex]\theta[/tex] is angle between F and d )=
Here , [tex]cos\theta=cos\ 33^o=0.84[/tex]
Putting value of [tex]cos\theta[/tex], force and distance in work done equation we get,
[tex]W=26\times 47\times 0.84=1026.48\ J.[/tex]
Hence , this is the required solution.
