Chapter SH, Problem 4.1APP

To determine

To Calculate: Work done on the couch.

Answer to Problem 4.1APP

Work done on the couch is $\underset{\_}{1600\text{ J}}$ .

Explanation of Solution

Given:

Force = $\text{400 N}$

Distance = $4.0\text{ m}$

Formula used:

Work done is given by,

  $W=Fd$

Where,F is force and disdistance.

Calculation:

Work done is calculated as:

  $\begin{array}{l}W=Fd\\ W=\left(400\text{ N}\right)\left(4.0\text{ m}\right)\\ W=1600\text{ J}\end{array}$

Conclusion:

Work done on the couch is $\underset{\_}{1600\text{ J}}$ .
