Question

problem #1: how much work is done by a person who uses a force of 27.5n to move a grocery cart 12.3m?
step 1: write down the equation needed to solve the problem.
step 2: insert all the known measurements into the equation.
step 3: solve. carefully enter numbers into your calculator.

Explanation:

Step1: Write the work formula

The formula for work is \(W = F\times d\), where \(W\) is work, \(F\) is force, and \(d\) is distance.

Step2: Substitute the values

Given \(F = 27.5N\) and \(d=12.3m\), substitute into the formula: \(W=27.5\times12.3\).

Step3: Calculate the result

\(27.5\times12.3=(27 + 0.5)\times12.3=27\times12.3+0.5\times12.3\).
\(27\times12.3 = 332.1\), \(0.5\times12.3 = 6.15\).
\(W=332.1+6.15=338.25J\).

Answer:

\(338.25J\)
