INFO

A particle undergoes three consecutive displacements given by vectors. All units are in mm:

Ď₁=2i-1j+0k

Ď₂=7i+7j-7k

Ďs=-1i+7j-5k

Help on how to format answers: units

(a) Find the resultant displacement vector of the particle (in terms of i, j, k):

mm.

(b) What is the magnitude of the resultant displacement? (Include the units in your answer)

Submit answer

(c) How far did the particle actually travel (ie what is the sum of the magnitudes of the individual displacements)? (Include the units in

your answer)
