A plane is being tracked by radar, and data is taken every second in polar coordinates
θ and r
t (sec) 200 202 204 206 208 210
θ (rad) 0.75 0.72 0.70 0.68 0.67 0.66
r (m) 5120 5370 5560 5800 6030 6240
1. Calculate the velocity of the plane as a function of time, where the velocity V is given by:
V= √r^2 + r(θ)^2.
Please compute the derivatives using the most accurate finite-difference method and comment on the choices you made (why did you choose to use a certain method at any given point).

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
