10. Bicyclists in the Tour de France reach speeds 34.0 miles per hour (mi/h) on flat sections of Measure the line with the ruler shown below . the road. What is the speed in (a) kilometers per hour (Km/h) and (b) meters per second a. What is your measurement ? (m/s)? b. How sig figs should your measurement contain and explain why? CENTIMETERS Practice : Express the following in scientific notation : 1. 5,200 sec =_ Part 3: Metric System, Unit Conversion and Scientific Notation Review 2. 0.00000365 m = Convert each of the following. Practice : Express the following in their expanded form 1 . 3072 8 = 1. 6.2 x 104 8 = _ 925 mm = m 2. 3.178 x 106 kg = _ m 2.16 mm = cm Part 4 - Graphing Review 46 m = Km Practice Finding the Slope Using this graph, please calculate the 26.86 miles/hour = m/s slope between the following points on 2 50 the graph 40 53 cm 2 = m 30 Position (m) 1. (1s, 10 m) and (0s, Om) N 2.7 hours = 2. (3s, 30m) and (2s, 20 m) 3 4 165 lbs = 3. (5s, 50m) and (1s, 10m) Time (s) 4. What observation can you make about the slope of this line? Vesna Vulovic survived the longest fall on record without a parachute when her plane exploded and she fell 6 miles, 551 yards. What is this distance in Km (Kilometers)
