Spaceship entering mars! okay guys so you have to open this file to read the question accuretely.. i have done some calculations but not sure if they are correct. So just this as best as i can, fist i figure out my semi-minor axis = a by 150km +150 KM +230 km =530km (major axis) now to...

FILE! shows diagrams! and hints!

Sending a spacecraft to mArs! Help! pLease! okay guys so you have to open this file to read the question accuretely.. i have done some calculations but not sure if they are correct. So just this as best as i can, fist i figure out my semi-minor axis = a by 150km +150 KM +230 km...

think about it if you throw it straight down its has an initial velocity only. In ideal physics your acceleration due to gravity should be only 9.8m/s on free falling objects.

In order to send a spacecraft to the planet Mars you will need to complete some basic orbital equations using Kepler's law of orbits. In the next few Mars Math Questions, we will look at ways engineers calculate this by introducing you to some basic equations and formulas. . Mars is 230...

orbital speed of mars! help!? Mars is 230 million km from the sun. It completes one orbit in a period of approximately 687 days. Calculate the orbital speed of Mars in mph. OK so gave me the formula which 2*pi*r/ Period r= distance from the planet to the sun. and cirmumference = 2*pi* r...

okay so my final answer will be just 107515.4004 km/hour converted into mph?

ok doc now I am just lost. i thought i had gotten the orbital speed by 2*3.1416*150000000km / 8766 hours (365 days) = 107515.4 km/h? do i i need to get the circumference of the Earth then divide by the 107515.4004 km/h (?

i don't understand why they give me the circumference formula!?

okay so redid it 2**3.1416*150 000 000 / 8766 hours = 107515.4004 km/hour?

Orbital speed of Earth! help! The Earth is 150 million km from the sun. IT completes one orbit in a period of approximately 365.25 days. Calculate the orbital speed of Earth in mph? OK guys so they give me the formula which is 2*pI*r /Period r= distance from the planet to the sun. and...

thanks for the help!

[b]1. A brass spring has an unstrained length of .18m and a spring constant of 1.3 E4 N/m. THe temperature increases from 21 cel to 135 cel. what is the magnitude of the compressional force that must be applied to the heated spring to bring it back to its original lenght!? [b]2. Linear...

okay so i got the amount of the water being displaced by multypling 1000 kg/m * .009m = 9kg at 1/3 of its height. so the rest 2/3 it would take 18 kg to fill the cube right..so i divided my mass of 18kg by my density of water to get my volume.. my volume i know was .3*.3 * X= i got x to...

[b]1. A hollow cubical box is .30 m. This box is floating in a lake 1/3 of its height beneath the surface. The walls of the box have neglibe thickness. Water is poured into box. what is the depth of the water in the box at the instant the box begins to sink? pwater= 1000kg/m3 Fb= Pfluid G V...
