from the totalpropelling force E we get theportion of the propelling forcewhich is used to cause thevelocity of the boat to increase.Therefore, according to Art. 33,we have: E- Ri = L didt (1) If we subtract the voltagewhich is required to overcomethe resistance of the circuit(namely, Ri) from the… … 3 4 S 6.78 hundredths of a secondFig. 43a. The general solution of thisdifferential equation,* subjectto the condition that the veloc-ity of the boat is zero at thebeginning (i = o when t = o),is: The general solution of thisdifferential equation,* subjectto the condition that the cur-rent in the…
