Question

A child pushes a box of blocks across the 15-foot long kitchen in his house with a force of 22 pounds atan angle of 310°. Calculate work done. Round your answer to the nearest tenth.

Answer 1

Step 1 :

In this question, we are meant to find the work done.

By definition, Work done is the product of Force and Displacement,

In this case, we have that:

`\begin{gathered} Work\text{ done = Force x Displacement} \\ W=(\text{ F x cos }\theta\text{ ) x Displacement} \end{gathered}`
`\begin{gathered} F\text{ = 22 pounds} \\ \theta=31^0 \\ \text{Displacement = 15 foot} \end{gathered}`
