To avoid using the variable "a" which of the following equations should you use?

a) v² (f) = v² (i) + 2aΔx
b) v (f) = v (i) +at
c) Δx = 1 / 2 ( v (f) + v (i) ) t
d) Δx = v (f) t - 1 / 2 at²

hi im pretty sure these are called 1D kinematic equations! thanks!

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

Phase changes are chemical changes. true or false

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as
