You hang a 400 gram mass on a spring and the spring stretches 16.0 cm. You then pull the mass down an additional 4.0 cm and let it go.   

a) Write an equation for the position of the mass as a function of time.

b) Where will the mass be located 4.0 seconds later?

c) What will its velocity be?

A mass of 100 g stretches a spring 5 cm. If the mass is set in motion from its equilibrium position with a downward velocity of 10 cm/s, and if there is no damping, determine the position u of the mass at any time t. (Use g = 9.8 m/s2  for the acceleration due to gravity. Let u(t), measured positive downward, denote the displacement in meters of the mass from its equilibrium position at time t seconds.) u(t) = When does...

Please show step by step explanation including all units. Part 1 Mass and Spring System You have a spring with an unknown spring constant. You attach a 10 gram mass and note that the spring stretches 1 cm. Then you remove that mass and attach a 20 gram mass and note that the spring stretches 2 cm. a) Find the slope of the line on F vs. x plot. That will be your spring constant. b) Then you pull the...

You hang a 10 kg mass off of a vertical spring with a spring constant k = 15 N/m. How much does the spring stretch? Then, you take the spring and lay it flat on a friction-less table, anchoring one end. You attach the same mass to free end, pull it back 0.25 meters from its equilibrium position, and let go. How fast is the mass going at the equilibrium position?

A spring is hung from the ceiling, and has a rest length of 43.0 cm. A block (mass = 0.374 kg) is attached to the spring. When we slowly let the mass down (being careful to not let it start oscillating), the spring stretches to a length of 58.4 cm. We then pull the mass down 3.0 cm below this position and let it go to begin oscillating. Assume the mass of the spring is negligible. a) What is the...

A mass of 1.5 kg stretches a spring 0.05 mm. The mass is in a medium that exerts a viscous resistance of 240 NNwhen the mass has a velocity of 6 msms. The viscous resistance is proportional to the speed of the object. Suppose the object is displaced an additional 0.06 mm and released. Find an function to express the object's displacement from the spring's natural position, in mm after tt seconds. Let positive displacements indicate a stretched spring, and...
