The unit of force in the SI system is the newton (N), which is defined in terms of basic SI units as 1N=1kg⋅m/s2. 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 1lb=1slug⋅ft/s2. Find the value of 15.0 N in pounds. Use the conversions 1 slug=14.59kg and 1ft=0.3048m.
Express your answer in pounds to three significant figures.
