Problem Set 1 : P roblem 1. Problem: Aviation pioneer Amelia Earhart weighed 118 lbs and stood 5 feet 8 inches tall. What was Earhart’s mass in slugs? Determine her mass and height in kg and m. Solution: First, denoting mass by M ,we igh tby W and gravitational acceleration by g , Earhart’s mass was M = W g = 118 lb 32 . 174 ft / sec 2 =3 . 668 slugs wherewemakeuseofthefac ttha t1lb=1s lug

Unformatted text preview: M to the SI system of units, we note that the conversion table tells us 1 slug = 14.594 kg. Thus, M = (3 . 668 slugs) w 14 . 594 kg slug W = 53 . 5 kg Finally, since there are 12 inches in a foot, Earhart’s height was H = 5.667 ft. From the conversion table, we have 1 ft = 0.3048 m, wherefore H = (5 . 667 ft) p . 3048 m ft Q = 1 . 73 m...
