The unit of force in the SI system is the newton (N), which is defined in terms of basic SI units as 1 N = 1 k g ⋅ m / s 2 . The unit of force in the British system is the pound (lb), which is defined in terms of the slug (British unit of mass), foot (ft), and second (s) as 1 l b = 1 slug ⋅ f t / s 2 .Find the value of 15.0N in pounds. Use the conversions 1 s l u g = 14.59 k g and 1 f t = .3048 m

Question

The unit of force in the SI system is the newton (N), which is defined in terms of basic SI units as   1  N  =  1  k  g  ⋅  m      /        s    2  . The unit of force in the British system is the pound (lb), which is defined in terms of the slug (British unit of mass), foot (ft), and second (s) as   1  l  b  =  1  slug   ⋅  f  t      /        s    2  .Find the value of 15.0N in pounds. Use the conversions   1  s  l  u  g  =  14.59  k  g   and   1  f  t  =  .3048  m

15N to lbsunit multipliers:  15  k  g     m      /        s    2    ⋅  (  1   slug       /    14.59  k  g  )  ⋅  (  1  f  t      /    0.3048  m  )  =  3.373   slug   f  t      /        s    2  since   1   slug   f  t      /        s    2    =  1  l  b,ans:   15  N  =  3.373  l  b  s
