PLS HURR One cylinder has a volume that is 8 cm less than 5 of the volume of a second cylinder. If the first cylinder's volume is 216 cm', what is the correct equation and value of x, the volume of the second cylinder? © x+8 = 216: x= 182cm? Ex-8 - 216; x= 198 cm 0 2x+8= 216; x - 238cm o x-8 - 216; x = 256cm

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).
