Question 2

Mathematics
1 answer:
s344n2d4d5 [400]3 years ago
7 0

The work is simply the dot product of the force and displacement (which I assume are given in Newtons and meters, respectively):

<em>W</em> = <em>F</em> • <em>d</em>

<em>W</em> = (5i + 3j - 2k) N • ((4i<em> - </em>j + 3k) m - (j + k) m)

<em>W</em> = (5i + 3j - 2k) • (4i - 2j + 2k) Nm

<em>W</em> = (20 - 6 - 4) Nm

<em>W</em> = 10 J
