T = 6 then = 6 then t= 1 I
-4.5 = a - 8 then a =
3 = 1 + p then p =
12 = I *-3 then x=
12 =
By then x =

How is this equation completed? i cannot find any examples in the book.

What is the correct decimal form of 12%

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).
