Amass of 1 slug is attached to a spring whose constant is 5 lb/ft. initially, the mass is released 1 foot below the equilibrium position with a downward velocity of 3 ft/s, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 2 times the instantaneous velocity. (a) find the equation of motion if the mass is driven by an external force equal to f(t)8 cos 2t + 2 sin 2t. x(t) = e^-t cos (2t) + 3 sin (2t) ft

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

hello! just here for points! though i wish i knew!
