A mass weighing 6 lb stretches a spring 5 in. If the mass is pushod upward, contracting the spring a distance of 7 in and then set in motion with a downward velocity of 5 ft/s, and if there is no damping and no other external force on the system, find the position u of the mass at any time t. Determine the frequency (w), period (T), amplitude (R), and phase (8) of the motion. NOTE: Enter eract answers. Use t as the independenf variable.

![**Problem Statement:**
A mass weighing 6 lb stretches a spring 5 in. If the mass is pushed upward, contracting the spring a distance of 7 in and then set in motion with a downward velocity of 5 ft/s, and if there is no damping and no other external force on the system, find the position \( u \) of the mass at any time \( t \). Determine the frequency (\( \omega_0 \)), period (\( T \)), amplitude (\( R \)), and phase (\( \delta \)) of the motion.
**Note:** Enter exact answers. Use \( t \) as the independent variable.
1. \( u(t) = \) [Input Field for the function]
2. \( \omega_0 = \) [Input Field in rad/s]
3. \( T = \) [Input Field in seconds]
4. \( R = \) [Input Field in feet]
5. \( \delta = \) [Input Field in radians]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa365e9f2-3057-4f86-b331-a3f6212260b4%2F24ca53f4-57fa-40be-842e-88a0805f53d6%2Fw68uiz_processed.jpeg&w=3840&q=75)
