Prof. K. took a Tesla Model S for a test drive. The car weighs 4,500 lb and can accelerate fra 0 to 60 mph in 2.27 seconds. The car has a 581 kW battery pack. Help Prof. K. determine th efficiency of the vehicle [Ans. to Check 55.5%]. Note: The equation we learned in class P = E ONLY APPLIES if velocity is constant. Use the steps below to guide your thought process. Develop a symbolic relationship for the force required to move the car forward. Compute the work done by the car (in Ib-ft). Calculate the power required to do this work (in kW).

Engineering Economy A company has determined the price and the monthly demand of its products are related by the equation D = √775 - p, where p is the price per unit in dollar and D, is the monthly demand. The associated fixed costs are $2,125 per month and the variable costs are $100/ unit. Use this information to answer the following: a)What is the optimal number of units that should be produced and sold each month? b) What is the maximum profit? c)Determine the value of D that represents the break-even point?
account_circle Science PhysicsQ&A LibraryA child’s toy consists of a m = 31 g monkey suspended from a spring of negligible mass and spring constant k. When the toy monkey is first hung on the spring and the system reaches equilibrium, the spring has stretched a distance of x = 17.6 cm, as shown in the diagram. This toy is so adorable you pull the monkey down an additional d = 7.6 cm from equilibrium and release it from rest, and smile with delight as it bounces playfully up and down. 1. Calculate the speed of the monkey, ve, in meters per second, as it passes through equilibrium. 2. Derive an expression for the total mechanical energy of the system as the monkey reaches the top of the motion, Etop, in terms of m, x, d, k, the maximum height above the bottom of the motion, hmax, and the variables available in the palette. 3. Calculate the maximum displacement, h, in centimeters, above the equilibrium position, that the monkey reaches. A child’s toy consists of a…
The mean weight of five complete computer stations is 167.2 pounds. The weights of four of the computer stations are 158.4 pounds, 162.8 pounds, 165.0 pounds, and 178.2 pounds respectively. What is the weight of the fifth computer station?
Recall the discussion on spacecraft from the chapter opener. The following problems consider a rocket launch from Earth’s surface. The force of gravity on the rocket is given by F(d)=−mk/d2, where m is the mass of the rocket, d is the distance of the rocket from the center of Earth, and k is a constant. 172. As the rocket travels away from Earth’s surface, there is a distance D where the rocket sheds some of its mass, since it no longer needs the excess fuel storage. We can write this function as F(d)=⎨(−m↓1 k / d^2) if d < D (−m↓2 k / d^2) if d ≥ D Is there a D value such that this function is continuous, assuming m1≠m2?

Two gaseous streams containing the same fluid enters a mixing chamber and leaves as a single stream. For the first gas the entrance conditions are A1=500 cm², v1=230 m/s, p1=1.60 kg/m³. For the second gas the entrance conditions are A2= 300 cm³, m2=8.84 kg/s, v2=0.502 m³/kg. The exit stream conditions is v3=130 m/s and v3=0.437 m3/kg. Determine the following: (a) the total mass flow leaving the chamber (kg/sec) (b) the velocity of the gas at 2. (m/sec)
Cathy Gwynn for a class project is analyzing a "Quick Shop" grocery store. The store emphasizes quick service, a limited assortment of grocery items, and higher prices. Cathy wants to see if the store hours (currently 0600 to 0100) can be changed to make the store more profitable. Time Period Daily Sales in the Time Period 0600-0700 $40 0700-0800 70 0800-0900 120 0900-1200 400 1200-1500 450 1500-1800 500 1800-2000 600 2000-2200 200 2200-2300 50 2300-2400 85 2400-0100 40 The cost ofthe groceries sold averages 65% of sales. The incremental cost to keep the store open, including the clerk's wage and other operating costs, is S23 per hour. To maximize profit, when should the store be opened, and when should it be closed?
You own a wheat warehouse with a capacity of 20,000bushels. At the beginning of month 1, you have 6,000 bushels of wheat. Each month, wheat can be bought and sold at theprice per 1000 bushels given in Table 46.The sequence of events during each month is as follows:a You observe your initial stock of wheat.b You can sell any amount of wheat up to your initialstock at the current month’s selling price.c You can buy (at the current month’s buying price) asmuch wheat as you want, subject to the warehouse sizelimitation.Your goal is to formulate an LP that can be used to determine how to maximize the profit earned over the next 10months
