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...
Please help me with this question. I got a m = m0 * e^(-gt/Vex) for part a, but not sure about it. Thanks for the help. 3. A multi-stage rocket of initial total mass mo is launched vertically from rest. The rocket engine burns fuel at a given constant rate k and sends out the exhaust at a constant speed vex. Neglect air resistance and assume a constant gravitational acceleration g a) Write down the expression for the mass of...
SectionDef Additional Problems 59. A rocket is launched vertically from rest, and it bums fuel at a constant rate of 136 kg/s. Exhaust gases are expelled with a speed of 5 25 x 10 m/s relative to the rocket. What is the magnitude of the thrust? A) 7.14 x 10°N V=5.25x10mts B) 3.64 % 10N m = 136 kg/s C) 2.59 x 10-2N D) 808 N Thrust - ? E) 38.6 N Ans: A Difficulty: Medium SectionDef Additional Problems
1. A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. (a) What is the initial acceleration of the rocket, assuming you can neglect air resistance? (b) After the rocket has been in flight for a while, burning and exhausting a lot of fuel, its mass has decreased to 1.20 x 105 kg, and...
