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. is equal to A smaller unit of force is dyne. 1 dyne is equal to How many dynes are there in ? 2. Convert a density of to 3. One light-year (ly) is the distance traveled by light in a year. Convert one light-year to meters using 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. b. C. 5. A 20 km long, 8 m wide, two-lane highway is to be paved with a 4 cm thick layer of asphalt. A fleet of three dump trucks is to be employed, each with an empty mass of 20 metric tons and a carrying capacity of 20 asphalt with a density of 0.72 will be used. Determine the following: a. the total volume of asphalt needed b. the number of dump truck loads required c. the gross mass of each truck
