I've got parts a-c and understand them. However, I do not understand the rest of the problem and how to solve for the answers in parts d and e. Any explanation would be helpful. (1 point) A mass of 4 kg stretches a spring 40 cm. The mass is acted on by an external force of F(t) = 97 cos(0.5t) N and moves in a medium that imparts a viscous force of 8 N when the speed of the mass...
ro A mass of 5 kg stretches a spring 20 cm. The mass is acted on by an external force of 10 sin N (newtons) and moves in a medium that imparts a viscous force of 4 N when the speed of the mass is 2 cm/s. If the mass is set in motion from its equilibrium position with an initial velocity of 9 cm/s, formulate the initial value problem describing the motion of the mass. (Use g = 9.8...
ITEMS JIIMARY 3. < Previous Ne A mass of 10 kg stretches a spring 14 cm. The mass is acted on by an external force of 4 sin(t/3) N and moves in a medium that imparts a viscous force of 3 N when the speed of the mass is 6 cm/s. If the mass is set in motion from its equilibrium position with an initial velocity of 2 cm/s, determine the position u of the mass at any time t....
please solve both. thank you! A mass of 1.25 kg stretches a spring 0.06 m. The mass is in a medium that exerts a viscous resistance of 56 N when the mass has a velocity of 2 . The viscous resistance is proportional to the speed of the object. Suppose the object is displaced an additional 0.03 m and released. Find an function to express the object's displacement from the spring's equilibrium position, in m after t seconds. Let positive...

4. A spring is stretch 10 cm by a force of 3 N. A mass of 2 kg is hung from the spring and is also attached to a viscous damper that exerts a force of 3 N when the velocity of the mass is 5 m/s. If the mass is pulled down 5 cm below its equilibrium position and given an initial donward velocity of 10 cm/s determine its position u at any time t. Find the quasi-frequency μ...

Please help solve this, using the equation to get through the problem. Additional information: where the initial position , the initial speed The above differential equation can also be written as: If , there is light damping where the solution has the form ( where r and w are two positive constants) or If there is heavy damping where, where and are two positive constants If there is critical damping where, where r is a positive constant d'y dy ma...
PART A PART B PART C PART D (1 point) A mass m = 4 kg is attached to both a spring with spring constant k = 197 N/m and a dash-pot with damping constant c=4N s/m. The mass is started in motion with initial position to 3 m and initial velocity vo = 6 m/s. Determine the position function r(t) in meters. x(1) Note that, in this problem, the motion of the spring is underdamped, therefore the solution can...
