Part 1 You are to use your car to estimate its engine efficiency. When the car has been filled totally with fuel set the trip counter to zero, drive until it is filled again and note the mileage covered. In table 1, below, it states the energy for Gasoline (Petrol). Diesel and LPG. Calculate the energy of the fuel used. For this exercise, we will ignore times stuck in traffic, etc.. and to estimate the overall efficiency of the fuel you use driving your car. The exercise is to determine values from actual situations. Next, research your vehicle and determine the weight in kg. likewise the estimated load (1 person approximately 80kg) use a practical estimate to how many are usually passengers - easy if only the driver. Energy + Table 1: Energy levels in different fuels. Storage Energy Specific Material | Туре MJ/kg Diesel Chemical 48 LPG Chemical 46.4 Gasoline Chemical 46.4 Energy density is measured in units of: J/m (1), or in SI, kg.m-s-2 (2) and you need to convert US Gal into kg. Thus, you can calculate the total energy that was available in the fuel used. Note: 2.2 lbs. = 1 kg and 1 gallon US = 2.80 kg You now need to calculate the energy needed to have moved your vehicle. The energy to move an object is given in the equation (3) below. E=m.d (3) Where distance, d, is measured in meters and mass, m, is measured in Newton's. 1N = 1 kg 9.81 (4) Efficiency is measured in percentages, %, and calculated: Eff - Energy Used/Energy Input (5) Comment on your calculations and derived answer. What does all this mean? Part II Repeat the above process but this time select a standard type of vehicle you see used that has a different fuel type to your own. Assume only 1 passenger at all time. What do these results tell you in comparison to Part I?

A engine part is built and shipped from a factory. The manager needs to estimate true proportion of parts (p) in the shipment that are mildly defective before the shipment goes out. He takes a sample of n=400n=400 parts and finds that 5% are mildly defective. He has 80% confidence that p lies in a confidence interval (a,b). What is the interval (a,b)?

A car is traveling along a road, and its engine is turning over with an angular velocity of +230 rad/s. The driver steps on the accelerator, and in a time of 8.0 s the angular velocity increases to +270 rad/s. (a) What would have been the angular displacement of the engine if its angular velocity had remained constant at the initial value of +230 rad/s during the entire 8.0-s interval? (b) What would have been the angular displacement if the...
