I am flying from Kansas City to Denver. My flight leaves Kansas City at 4:30 pm. I land in Denver at 4:25 pm on the same day. Denver and Kansas city are 320 miles apart. How is this possible?
You and your pen pal from Mars are comparing to see who is taller. You write to yourfriend that you are 1.7018 m tall. Your pen pal writes back that they are 58.19 orfzagstall. An orfzag is a Martian unit equivalent to exactly 26 glibchoms (another Martianunit). One meter is approximately 936.36 glibchoms. Who is taller? Report bothheights in meters to the appropriate number of significant figures. Show yourreasoning and all work.

Question 15. An object is launched on the moon at 16 feet per second (f/s) from a
1152-foot tall tower. The equation for the object's height s at time t seconds after
launch is s(t)=-16t^2+16t+1152, where s is in feet. When does the object strike the
moon's surface and why?

- A room has dimensions of 9.8 meters by 8.3 meters by 3.5 meters. Air has a mass density of 1.3 kilograms per cubic meter. Using 9.8 meters per second squared for "g", the acceleration due to gravity, calculate the weight of air in the room in Newtons.arrow_forwardOn a certain mountain, the elevation z above a point (r, y) in an ry-plane at sea level is z = 2000 – 0.02.² – 0.04y², where x, y, and z are in meters.

- You have a dream you are driving across the country. In your dream, you leave Kala- mazoo at 9 a.m. on a tour along 194: you drive to Chicago, Milwaukee, Minneapolis, and Fargo. You arrive to Fargo at 8 p.m. You spent your entire trip staring out the window enjoying the sights, and (this is a dream, remember?) you didn't get hurt. According to the trip counter on your odometer, you have travelled 813 miles on your trip. The speed limit was between 55 mph and 70 mph on your trip. Were you ever speeding?

- There is one part to this question. I need to know the days. Thank you!arrow_forwardThe earth revolves around the sun in exactly 365 1/4 days which is equivalent to 1 year. To make up for the loss of 1/4 day, the calendar was adjusted so that we have a leap year for every 4 years. If the earth were to speed in its motion slightly so that a year would be completed in exactly 365 days and 6 hours, how often would we need to have a leap year?arrow_forwardfriend are traveling the world and are currently in a city located precisely on the Earth's equator.
