Question

If 150 Joules of work is needed to move a box 1000 cm, calculate the force that was used?

Answer 1

Answer:

$\large{ \tt{☄ EXPLANATION}} :$

• We're provided : Work ( W ) = 150 J & Displacement ( D ) = 1000 cm & We're asked to find out the force that was used. Firstly, Notice that we're provided the unit of Displacement as centimetre so we have to convert 1000 cm into m. Displacement ( D ) = $\frac{1000}{ 100} = 10$ m

$\large{ \tt{♡ \: LET'S \: GET \: STARTED}} :$

• Work is defined as the product of force and Displacement. By definition ,

$\large{ \boxed{ \tt{❃ \: WORK ( \: W \: ) = FORCE\: ( \: F) \times DISPLACEMENT \: ( \: D \: )}}}$

- Plug the values and then simplify !

$\large{ \bf{↦ \: 150 = F \times 10}}$

$\large{ \bf{↦F\times 10 = 150}}$

$\large{ \bf{↦ \: F = \frac{150}{10}}}$

$\large {\bf{↦F = \boxed{ \bf{15} \: N}}}$

$\boxed{ \boxed{ \large{ \tt{✤ \: OUR \: FINAL \: ANSWER : \boxed{ \bf{15 \: n}}}}}}$
