Question

a body moves 6M North 18M east and 10 M vertically upwards, what is the what is its resultant displacement from initial position

Answer 1

Let body is at origin initially

then it moves 16 m in y direction

and 18 m in -x direction

and 10 m in z direction

so it's position vector is -18i+6j+10k

and magnitude of displacement = ✓(-18^2+6^2+10^2) = ✓460

thanks
