Answer the following problems showing all work. Showing all work means using the steps stated in [[Dimensional Analysis Notes]] and math rules.<br> <br> Conversion factors 1 in = 2.54 cm <br> <br> 1. Remy that curious cat can run 31.2km/hr. How fast can he go in ft/sec? <br> <br> <br> <br> <br> <br> <br> <br> <br> 2. If Remy wanted to run 4.5E3m, how long (in days) will it take him? Assume he run at same speed as above problem.<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 3. Duxbury football team can eat 1.5 hamburgers/(player-hr). How many burgers will the team eat if there are 11 players and they eat for 2.5 hrs?<br> <br> <br> <br> <br> <br> <br> <br> 4. The density of the hamburger that the Duxbury football eat was D = 1.24g/cm<sup>3</sup>. Assume it each hamburger was 210.g, what is the volume of the hamburger. (We are assuming the hamburger is one substance.)<br> <br> <br> <br> <br> <br> <br> <br> Answer: 1) 28.4ft/sec , 2) 6.0E-3 days , 3) 41 hamburgers<br> 4) 169cm<sup>3</sup> for 1 hamburger, if assumed 41 hamburgers (from Q3) then 6.94E3 cm<sup>3</sup> or 6.94 L<br>
