- y(t)=y0+vy0t-0.5gt2 1) Using algebra shows that a meteor, initially at rest(vy0=0) will take about 20 minutes to fall from an altitudeof 7,000 km as shown in the diagram to the right. Note thatthe change in y is negative and you will need to convert kminto meters for the units to work out correctly. The calculation from problem 1) is incorrect though. Thereason being that acceleration is not constant. Theacceleration due to gravity varies with height. When near thesurface of the Earth objects accelerate at g = 9.8 m/s2 however when the meteor is further away from the Earth it’sthe acceleration is less. The meteors acceleration is actually given by the formula. ay=-G(M/r2)We would like to be able to make meaningful interpretations of variations in the acceleration due to gravity, g, as small as 0.1 mgal. How accurate must our knowledge of the latitude of our gravity stations be? (A “gravity station" is just a location at which you make a gravity measurement.) You can assume your latitude is 45°.Mehul
- Solution from part A: E=-KE = PE/2 Solution from part B: =3/2kt a. (NOTE: Treat the cloud as two equal masses interacting gravitationally across a distance equal to the radius of the cloud.) Use your result from part a to write down the condition for gravitational collapse in terms of the kinetic and potential energies (NOTE: This condition is an INEQUALITY) b. Use your result from part b in order to replace the kinetic energy with its temperature equivalent in your expression for the collapse condition. c. Solve the expression in ii above for the mass.thank you for this explanation. however, i don't really see how it answers the question: does it match the reasoning?How do you get the coordinates from here?
