Question

A particle starts from rest at point A(1, 2,-3)m and reaches at point Blank(3, 4,5)m. The magnitude of displacement of particle is

Answer 1

A=(1,2,-3)

B=(3,4,5)

displacement=final position-initial position

=B-A

=(2,2,8)

x=2

y=2

z=8

Magnitude of displacement=√(x²+y²+z²)

=√4+4+64

=√72

Hope this helps
