two stage rocket physics problem

A rocket in its simplest form is a chamber enclosing a gas under pressure. The compatibility with smart phones, iPads, other tablets, and Chromebooks make it a perfect tool for use in a 1:1 classroom. There is a small hot spot in the top-left corner. From that instant, it begins to move upwards with a constant acceleration. Then the first stage engine drops off revealing a second engine. A large fraction (typically 90%) of the mass of a rocket is propellant, thus it is important to consider the change in mass of the vehicle as it accelerates. In all such problems, the solution involves thought and good problem-solving strategies (draw a picture, list what you know, list pertinent equations, etc.). Checking can be done by stepping the simulation backwards to the specified time on the graph.

A 725-kg two-stage rocket is traveling at a speed of \({\bf{6}}{\bf{.60 \times 1}}{{\bf{0}}^{\bf{3}}}\;{\bf{m/s}}\) away from Earth when a predesigned explosion separates the rocket into two sections of equal mass that then move with a speed of \({\bf{2}}{\bf{.80 \times 1}}{{\bf{0}}^{\bf{3}}}\;{\bf{m/s}}\)relative to each other along the original line of motion. the rate of pressure decrease drops. Thus, the speed of fragment A is \(8.00 \times {10^{ - 3}}\;{\rm{m/s}}\), and the speed of fragment B is \(5.20 \times {10^3}\;{\rm{m/s}}\). The momentum of the rocket after the explosion is calculated as follows: \(\begin{array}{c}{p_{\rm{f}}} = {m_{\rm{A}}}{v_{\rm{A}}} + {m_{\rm{B}}}{v_{\rm{B}}}\\ = {m_{\rm{A}}}{v_{\rm{A}}} + {m_{\rm{B}}}\left( {{v_{\rm{A}}} - {v_{{\rm{AB}}}}} \right)\\ = {m_{\rm{A}}}{v_{\rm{A}}} + {m_{\rm{B}}}{v_{\rm{A}}} - {m_{\rm{B}}}{v_{{\rm{AB}}}}\\ = \left( {{m_{\rm{A}}} + {m_{\rm{B}}}} \right){v_{\rm{A}}} - {m_{\rm{B}}}{v_{{\rm{AB}}}}\\ = m{v_{\rm{A}}} - \frac{{m{v_{{\rm{AB}}}}}}{2}\end{array}\). In fact, you get a lot of blank sheets of paper. If the rocket of total mass 8M (say) had just one engine and it burned 7M of its fuel, it seems as if the same effect would be obtained as firing 3 identical rockets simultaneously. Speed of the rocket, \(v = 6.60 \times {10^3}\;{\rm{m/s}}\). (b) For comparison, a nuclear bomb could release about \(4.0 \times {10^{16}}\;{\rm{J}}\). More powerful engines like the Merlin, RS-25, or F-1 engines use more complex combustion cycles that siphon off some of the combustion's energy to power the pumps. The collision could pose a threat to life on Earth. Map for more information. The Two Stage Rocket Interactive is an adjustable-size file that displays nicely on smart phones, on tablets such as the iPad, on Chromebooks, and on laptops and desktops.

A child in a boat throws a 5.30-kg package out horizontally with a speed of 10.0 m/s Fig. Like a lot of physics word problems, there is more than one path to the final answer. Users are also granted the right to copy the . the water, the pressure and exhaust velocity drop, and thus. Typical margins in structural design are 40%. Astronomers estimate that a 2.0-km-diameter asteroid collides with the Earth once every million years. Reproduction of material from this website without written permission is strictly prohibited. Note however, that from 10 to 16 seconds, the rocket continues moving upward (the velocity values are positive). \(7.11 \times {10^8}\;{\rm{J}}\) of energy was supplied by the explosion. Resuming: - Closed system, don't loose mass: use F= dp/dpt = m*dv/dt + v*dm/dt. Solution. . It takes an enormous amount of energy (and therefore, fuel and money) to send a payload into space. The key is to solve two problems - one for stage 1 and the other for stage 2. We can now look at the role of specific impulse in setting the performance of a rocket. Teaching Physics with the Physics Suite The momentum of the rocket before the explosion is \({p_{\rm{i}}} = mv\). A two-stage rocket is traveling at 1200 m/s with respect to the earth when the first stage runs out of fuel. Since the values used in the simulation are randomly selected, it is most likely that side-by-side students in a classroom will have different values. After a little time, that engine will fire and take the rocket up even higher. The second factor is the rate at which mass is ejected from the rocket.
