Question 1:
A radar station located at (0,0) makes two radar contacts. Contact a is made 14 east of north at 7.6 km. Another radar contact, b is made 27 west of south at 5.1 km.
(a) Sketch a scale diagram of both radar contacts, a and b.
(b) How far is b from a?
(c) At what heading relative to north is contact a from contact b?
Question 2:
A robotic arm moves a component in 3D space from position a at (1,2,1) m to position b at (3,3,2) m. The force required to move the component can be described by the force vector (60,-10,30) N.
(a) Find the displacement vector that describes the movement of the component from position a to position b. Give your answer in ˆ i, ˆ j, ˆ k notation.
(b) What work is done by the robotic arm in moving the component?
