Una persona tiene 45 años de edad y una masa de 78 kg. ¿Cuántas horas ha vivido? ¿Cuál es peso en slug+?

I will answer this in English.

He has 45 years.

a year has 365 days.

a day has 24 hours.

So he has:

45*365*24  hours = 394,200 hours.

His mass is 78 kg,

And we know that 1 slug = 1lbf*ft/s^2

Then, the first step is transform the 78 kg into lbf.

1kg = 2.2 lbf.

then 78kg = 78*2.2 lbf = 171.6lbf.

Now, the weight is m*g, where m is the mass and g is the gravitational acceleration, in this case the gravitational acceleration in ft/s^2 is:

g =  32.2 ft/s^2

Then the weight in slugs is:

W = 32.2ft/s^2*171.6lbf = 5,525.5 slugs
