Answer:

1. Distance = Length of path travelled

=AB+BC

=15+9

=24km

Displacement = Shortest path from initial to final position

=AC

=(AB)2+(BC)2{Pythagoras Theorem}

=225+81

=17.5km

Since, F = constant, we can use.

W=F∙S

2. Here, S=rf−ri=(i^+2j^+3k^)−(2i^+3j^+4k^)

=(−i^−j^−k^)

∴W=(2i^+3j^+4k^)∙(−i^−j^−k^)

=−2−3−4=−9J
