#1B, A 40 Kg mass hanging from a spring stretches the spring by 0.06 m. spring constant = K = 3270 N/M angular frequency № = 9.042 radis Write the equation of motion, x(t) = A cos(oot + D), for the spring/mass system in Problem #1B, if the maximum deflection of the vibrating mass is 8 cm, and the position of the mass at t=0 sec is x = -2.2 cm. (In other words, calculate A, w and D). calculate A) the magnitude and direction of the velocity of the mass at t = 0.3 sec, and B) the position of the mass at t = 0.3 sec.
