1. If a person's hair grows at .35 mm per day, what is this growth rate in te 1 mm (millimeters)= .1 cm (centimeters) 2.54 cm = 1 inch 12 inches = 1 foot 365 days in a year 100 years in a century 2. A hill with a 12% grade is one that rises 12 m vertically for every 100 m of distance in the horizontal direction. At what angle is the hill inclined about the horizontal? 3. The drawing shows a triple jump in checkers. If each square is 4 cm per side, what is the magnitude of the displacement vector after the jump? 4. An Australian emu is running due north in a straight line at a speed of 13.0 m/s and slows down to 10.6 m/s in 4.0 s. What is the direction of the bird's acceleration? Assuming the acceleration stays the same, what is the bird's velocity after another 2.0 s?
