4. You work for a toy company, and you're designing a spring-launched model rocket. The launching...
I'd question 40 please.
39. Rocket Motion Suppose a small single-stage rocket of total mass m) is launched vertically, the positive direction is upward, the air resistance is linear, and the rocket consumes its fuel at a constant rate. In Problem 22 of Exercises 1.3 you were asked to use Newton's second law of motion in the form given in (17) of that exercise set to show that a mathematical model for the velocity v(t) of the rocket is given...
Part A You have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 12-m-high hill, then descends 17 m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.1 m and that a loaded car will have a maximum mass of 440 kg. For safety reasons, the spring constant should be 12 % larger than the minimum needed for the car to...
PLEASE SHOW WORK AND ANSWER ALL PARTS. WHEN I ASKED THE
SECTIONS SEPARATELY THE ANSWERS DID NOT MATCH, THANK
YOU!!!
All of the questions on this concern a space station, consisting
of a long thin uniform rod of mass 4.4 x
106kg and length 171 meters,
with two identical uniform hollow spheres, each of mass 1.3
x 106 kg and radius 57 meters,
attached at the ends of the rod, as shown below. Note that none
of the diagrams shown...
part F and G
The function describing the predicted velocity as a function of time, u(t), for a student-designed prototype two-stage model rocket a = 3.0 m/s. B = -24 m/s, and y = 54 m/s. Due to ignition rates of the fuel in the two stages and external forces acting on th minimum and a local maximum during the time interval. Part F Determine the times at which u(t) has a local minimum and maximum. Express your answer as...
mperial Valley College PROJECT #3 You may work in groups of up to 4 students. Each group turns in one homework, wnitten on separate paper e,aat in tiny writing on this sheetl with llwri and all stens shoan doack All students in each group recee the same grade This assignment is due ot the begrring 덱 dass on"huidey July 27 (day of Find Exon This project is worth o total f 40points Homework will be graded not only on correctness,...
Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
