While taking a break from the Extreme Beer Fest in Boston, you decide to do something educational and walk the Freedom Trail. You want to go from the Old North Church to the Bunker Hill Momument. First, you amble 0.33 miles at a polar angle of 159 degrees (0.33mi Z159). Next, you stumble 0.37 miles at a polar angle of 127 degrees (0.37mi Z127°). Finally, you crawl 0.52 miles at a polar angle of 80 degrees (0.52 mi 280°). What is the overall displacement from your starting point at the Old North Church? Express your answer in polar notation.

A differential equation encountered in the vibration of beams is d4ydx4=2D where x = distance measured along the beam; [x]=[L] y = displacement of the beam; [y]=[L] = circular frequency of vibration; []=[T1] = mass of the beam per unit length; []=[ML1] D = bending rigidity of beam; [D]=[FL2] Show that the equation is dimensionally homogeneous. Note that [F]=[MLT2] see Eq. (1.21:).
How are you getting 16 mm at the end for an answer , "HX83=219X10^3/164.909".................is that your diving by f/a and multiplying by 83 to get H , im just no sure what you did to get 16 ?.
The speed of your automobile has a huge effect on fuel consumption. Traveling at 65 miles per hour (mph) instead of 55 mph can consume almost 20% more fuel. As a general rule, for every mile per hour over 55, you lose 2% in fuel economy. For example, if your automobile gets 30 miles per gallon at 55 mph, the fuel consumption is 21 miles per gallon at 70 mph. If you take a 400-mile trip and your average speed is 80 mph rather than the posted speed limit of 70 mph, what is the extra cost of fuel if gasoline costs $4.00 per gallon? Your car gets 30 miles per gallon (mpg) at 60 mph.
Experiment #2: Acceleration vs. Mass Link https://phet.colorado.edu/sims/html/forces-and-motion-basics/latest/forces-and-motion-basics_en.html In this lab you will determine the relationship between acceleration and mass. Choose an Applied Force at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Mass. Graph Acceleration vs. Mass. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Mass information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best – linear, exponential, polynomial, etc … Add a copy of you graph below the table Applied Force (N) Mass (kg) Acceleration (m/s²)
: You are abducted by aliens and find yourself locked in a large room on some strangeplanet. To pass the time, you decide to do some experiments using a ball-and-chain thatyou find on the floor. You make the following estimates:mBALL  7 kg ,mCHAIN  0.5 kg, and CHAIN  2 m .(a) When you hold the free end of the chain above your head and allow the ball to swinglike a pendulum, you use your wristwatch to measure the period asT  4 s. What is theacceleration due to gravity on this planet?(b) If the ball accidentally hits a wall, how long does it take for this jolt in the chain totravel up to your hand?
The fuel gage for a gasoline tank in a car reads proportional to its bottom gage.The tank is 35cm deep and theSpecific gravity of gasoline is 0.68.a) What is the gage reading when the tank is filled with gasoline?b)If the tank is accidentally contaminated with 3cm of water,how many cm of air remains on top of the tank when the gage reads "FULL"?
Study the table to the right and then answer these questions by filling in the blank columns in the table.1. Convert the miles per gallon figures in the table tokilometers per liter (kpl).2. How many liters (and how many gallons) of gasolinewould each type of car use annually if it were driven19,300 kilometers (12,000 miles) per year?3. How many kilograms (and how many pounds) of carbon dioxide would be released into the atmosphereannually by each car, based on the fuel consumptioncalculated in question 2? Assume that the combustion of gasoline releases 2.3 kilograms of CO2 per liter(19 pounds per gallon).
Most of you have seen car advertisements where the car manufacturerbrags about how fast one of its cars can go from 0 to 100 km/h. Accordingto the manufacturer, the BMW 750iL model can go from 0 to 100 km/h in6.7 seconds. This performance is usually measured on a test track. The engine in the car is rated at 243 kW at 5000 rpm. The car has a reported weight of 23 kN . Is the claim by the manufacturer justifiable? Well, to answer this question you may agree it would be more fun to drive toa BMW dealership and take the car for a test run on a racing track. But let us answer this question with the knowledge you have gained so far in this course. We need to make some assumptions first; we can assume that the driver weighs 900 N and the reported weight of the car includes enough gasoline for this test. Next, we convert the speed and the mass values into appropriate units.
On Mars, the acceleration due to gravity is 6.64 m/s2. What would a rock’s speed be 6 s after you dropped it on Mars?
In the movie Back to the Future, Marty travels back in time to 1955. In 1955, the only available light bulbs in the United States were incandescent bulbs. Assume that last year, you traveled back in time to 1955 and changed all the light bulbs in a single average American household (45 light bulbs) from 75-watt incandescent bulbs to the corresponding 17-watt LED bulbs. The estimated usage is 3 hours per day , at a cost of $0.11 per kilowatt-hour . Based on energy cost alone - not considering the cost to replace any light bulbs and not considering any changes in energy cost with time - how much money in dollars would this household have saved over a 66-year time span (from 1955 to 2021) by changing from incandescent to LED bulbs?
Graph below represents the force on a 12 kg air mass as it passes through a jet engine. Immediately after entering the engine, the force is 9,039 N, and the force tapers linearly to zero once the air reaches the back of the engine 2.3 m later. If the air enters the engine with velocity 252 m/s, what is its exit velocity? (Please answer to the fourth decimal place - i.e 14.3225)
