Answer:
Option (d) will be the correct option
Explanation:
We know that 1 horse power is equal to 745.7 watt
We have to convert this J/sec to foot-pound/sec
Other unit of watt is joule/sec
So 1 horse power = 745.7 J/sec
We know that 1 joule = 0.7375 foot-pond
So 745.7 J = [tex]745.7\times 0.7375=550fott-pound[/tex]
So 745.7 j/sec = 550 foot-pound/sec = 550 ft-lb
So option (d) is the correct option
