Question

Moe is carrying and supporting a large crate by exerting 1000 N. He is walking at constant velocity across a level, horizontal floor. If he covers a distance of 10 meters, howmuch work does he do on the crate? Use g = 10m/s2 if needed. Ignore friction between Moe and the crate.1. Moe did no work on the crate.2. 100 Joules3. 10,000 Joules4. We need the speed of the crate, which isnot given.5. 1,000 Joules

Answer 1

the Given that applied force on the crate is F = 1000 N and the displacement is

d = 10 m .

The work done will be

$W=Fd$

Substituting the values, the work done will be

$\begin{gathered} W=1000\times10 \\ =10000\text{ J} \end{gathered}$

Thus, the work done is 10000 J.
