Problem Set 1: Problem 1. Problem: During his playing career, Pittsburgh Steelers football great “Mean” Joe Greene weighed 260 lbs and stood 6 feet 4 inches tall. What was “Mean” Joe’s mass in slugs? Determine his mass and height in kg and m, respectively. Solution: First, denoting mass by M ,we igh tby W and gravitational acceleration by g ,G reene sma s s during his career was M = W g = 260 lb 32 . 174 ft

Unformatted text preview: ft/sec 2 . Now, to convert M to the SI system of units, we note that the conversion table tells us 1 slug = 14.594 kg. Thus, M = (8 . 08 slugs) w 14 . 594 kg slug W = 117 . 9 kg Finally, since there are 12 inches in a foot, Greenes height was H = 6.333 ft. From the conversion table, we have 1 ft = 0.3048 m, wherefore H = (6 . 333 ft) p . 3048 m ft Q = 1 . 93 m...
