Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).

Question 2 of 102 pointsthe temperature is 45°f. the temperature will decrease by 2°f each hour. leth be the number of hours.when will the temperature be below 32°f? write an inequality for this problem.oa. 45 + 2h 32b. 45 + 2h< 32o c. 45 - 2h< 32od. 45 - 2hs 32
