1. The SI Unit of force is newton, represented by a capital letter N. One newton of force gives a 1.0 kg body and acceleration of 1.0 m/s². 1N is equal to 1kg. m/s². A smaller unit of force is dyne. 1 dyne is equal to 1g. cm/s². How many dynes are there in 1N? 2. Convert a density of 2.79g/cm³ to kg/m³ 3. One light-year (ly) is the distance traveled by light in a year. Convert one light-year to meters using 3 x 10° m/s for the speed of light. (Hint: d=vt) 4. Imagine that you are driving your car in Canada. As you're driving along, you notice that the speed limit signs have numbers like 120 (on the highway) and 50 (in the city). As you start to speed up, you realize that the signs are in km/hour. Unfortunately, your speedometer only reads in mi/hour. Figure out how fast you're allowed to go if the sign says: a. 120km/hr b. 75 km/hr c. 50 km/hr
