1. A 96 Ib weight stretches a spring 3.2 ft in equilibrium. It is attached to a dashpot with damping constant c=18 lb-sec/ft. The weight is initially displaced 15 inches below equilibrium and given a downward velocity of 12 ft/sec. Find its displacement for t > 0.
2. A 16 lb weight stretches a spring 6 inches in equilibrium. It is attached to a damping mechanism with constant c. Find all values of e such that the free vibration of the weight has infinitely many oscillations.

An object weighing 305 N in air isimmersed in water after being tied to a string connected to abalance. The scale now reads 255 N. Find the density of the object
How much power must you exert to horizontally drag a 20.0 kg table 14.0 m across a brick floor in 40.0 s at constant velocity, assuming the coefficient of kinetic friction between table and floor is 0.550.
So I have a spring with a ball on it. I measure how many times it oscillates 10 times and I measure those 10 times at 11.6 seconds which means one time it takes is 1.16 seconds. How do I find the spring constant
