A sled is being pulled with a force of 120 N at an angle of 35o with the horizontal. How far is the sled pulled if 1100 J of work is done? (11.2 m)

Respuesta :

Answer:11.2 m

Step-by-step explanation:

Given

Force Applied [tex]F=120 N[/tex]

inclination [tex]\theta =35^{\circ}[/tex]

Force has two components here i.e. [tex]F\cos \theta [/tex] and [tex]F\sin \theta [/tex]

[tex]F\cos \theta [/tex] will will do work

Work done is given by force time displacement

[tex]W=120\cdot \cos 35\times s[/tex]

[tex]1100=120\times \cos 35\times s[/tex]

[tex]s=11.19\approx 11.2 m[/tex]
