A mass-spring system oscillates with an amplitude of 8.7 cm. If the force constant of the spring of 300 N/m and the mass is 0.44 kg, what is the magnitude of the maximum acceleration of the mass in m/s%? Enter a number with one digit behind the decimal point. > | Question 7 1 pts A 0.500 kg mass is attached to a spring of constant 150 N/m. A driving force F(t) = ( 12.0N) cos(wt) is applied to the mass, and the damping coefficient b is 6.00 Ns/m. What is the amplitude (in cm) of the steady-state motion if w is equal to half of the natural frequency wg of the system? Enter a number with one digit behind the decimal point. | Question 8 1 pts The mechanical energy of a mass-spring system is 0.196 J. If the force constant of the spring of 153 N/m and the mass is 0.61 kg, what is the amplitude of the oscillatory motion in cm? Enter a number with one digit behind the decimal point
