A mass of 1.5 kg stretches a spring 0.05 mm. The mass is in a
medium that exerts a viscous resistance of 240 NNwhen the mass has
a velocity of 6 msms. The viscous resistance is proportional to the
speed of the object.
Suppose the object is displaced an additional 0.06 mm and
released.
Find an function to express the object's displacement from the
spring's natural position, in mm after tt seconds. Let
positive displacements indicate a stretched spring, and use 9.8
ms2ms2 as the acceleration due to gravity.

Questions Determine whether or not the vector field is conservative. If it is conservative, find a vector f f such that . F→=∇f. → F ( x , y , z ) =< y cos x y, x cos x y , − sin z > F→ conservative. A potential function for → F F→ is f ( x , y , z ) = f(x,y,z)= + K. (Type "DNE" if → F F→ is not conservative.)
