A one fifth 1 5-kg mass is attached to a spring with stiffness 2525 N/m. The damping constant for the system is 44 N-sec/m. If the mass is moved StartFraction 12 Over 5 EndFraction 12 5 m to the left of equilibrium and given an initial rightwardrightward velocity of 1919 m/sec, determine the equation of motion of the mass and give its damping factor, quasiperiod, and quasifrequency.

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
