2. A 130 N force is applied on the handle of a lawn mower. The handle makes an angle 50 with the ground as the lawnmower moves across the ground. Determine the following a. the magnitude of the component of the force acting in the direction of motion b. the work done by this force if the lawnmower is pushed 15 m across the ground​

Answer:-

  • Force=130N
  • Displacement=15m

We know that

[tex]\boxed{\sf Work\:Done=Force\times Didplacement}[/tex]

[tex]\sf\longmapsto Work\:done=130\times 15[/tex]

[tex]\sf\longmapsto Work\:done=1950J[/tex]

Note:-

  • SI unit of work done is Joules(J)
