​

Answer 1

$\mathfrak{Question}$

How much work will be done on displaying grass roller of 250 kg by 4 mt horizontally by applying 40 Newton force in the direction making angle 30°.

$\mathfrak{Given}$

$\twoheadrightarrow$ Mass (m) = 250kg

$\twoheadrightarrow$ Displacement (s)= 4m

$\twoheadrightarrow$ Force (F) = 40N

$\twoheadrightarrow$Angle ($\theta$ ) = 30⁰

$\mathfrak{Answer}$

$\hookrightarrow$ $\mathsf{ Work \: Done = \: Fs \cos\theta}$

$\hookrightarrow$ $\mathsf{ Work \: Done = 40 × 4 × \cos30⁰}$

$\hookrightarrow$ $\mathsf{ Work \: Done = 866.02540378 Nm}$

$\hookrightarrow$ $\mathsf{ Work \: Done = 866.025 J}$

Answer 2

Answer:

- Work Done = FS cos 0

- Work Done= 40×4× cos 30°

- Work Done= 866.02540378 N

- Work Done= 866.025 J.
