An object of mass is released from rest a distance 3.2R above the surface of a planet, which has no atmosphere, of mass and radius . It strikes the surface of the planet with a speed given by v=c (sqt GM/R) , where c is a constant What is the numerical value of ?
a) Given the following ideal Atwood machine in an elevator accelerating down at ae = 4.9 m/s2, with m1 = 10 gram (two nickels) and m2 = 5 gram (one nickel) as shown, what is the tension T in the string in millinewton (mN)? (Hint: the upward arrow on ae is correct and just means use "positive is up" conventions for the elevator itself, so here we have ae = -4.9 m/s2 to be put into Einstein's rule that we discussed.) b) Exact same Atwood machine as the previous problem (two nickels and a nickel in an elevator accelerating down at 4.9 m/s2), but now how much time (s) does it take m1, starting from rest, to fall 25 cm relative to the inside of the elevator? I labeled it a and b because they are connected to each other. Please help, thanks!
Given that a satellite has to be shifted 300km further from Earth than it's original geosynchronous orbit (that has period = 24hrs & radial distance of 42300km from center of the planet). Using most of the derivations from Newton's 2nd Law, a. what is the orbital period of the new orbit after shifting in hrs? b. How much energy would it take to move to new orbit if mass of satellite = 6350kg ? Givens -> Mass of earth = 5.98x10^24 kg G= 6.673x10^-11 (you can use other constants)
A spacecraft cruising in space at a constant velocity of 2000 ft/s has a mass of 25,000 lbm. To slow down the spacecraft, a solid fuel rocket is fired, and the combustion gases leave the rocket at a constant rate of 150 lbm/s at a velocity of 5000 ft/s in the same direction as the spacecraft for a period of 5 s. Assuming the mass of the spacecraft remains constant, determine (a) the deceleration of the spacecraft during this 5-s period, (b) the change of velocity of the spacecraft during this time period, and (c) the thrust exerted on the spacecraft.
A group of Loyola students decided to depart from Earth after graduation to find work on Mars. Before building a shuttle, they conducted careful calculations. A model for the velocity of the shuttle, from liftoff at t = 0 s until the solid rocket boosters were jettisoned at t = 84.8 s, is given by ?(?)=0.001111333?^3−0.085745?^2+30.69?+9.71 (in feet per second). Using this model, estimate the global maximum value =?and global minimum value =?
Our solar system is roughly 2.2 x 1020 m away from the center of the Milky Way galaxy, and the system is moving at roughly 231.4 km/s around the galaxy's center. Since most of the galaxy's mass is near its center (and we are on an outer arm of this spiral galaxy), let's model the galaxy has a spherical mass distribution (like a single, giant star that our system is orbiting around). What is the mass of the galaxy (according to our rough, spherical model)? Obviously, this will be a VERY big answer, and so enter in your answer to the order of 1040 kg. In other words, calculate the answer, and then divide by 1040 and then enter in the result. BTW - by assuming that all mass in the galaxy is made up of stars that are about the same mass as our sun, it isn't too hard to then estimate how many stars are in the galaxy!). As an another aside, some measurements and observations that we have taken in Astronomy suggests that in reality, stars only make up a fraction of the total mass

Answer without rounding off: (COLLAB Gauss's Law for Mass) Journey through the Center of the Earth. A 1024-kg blue ball is dropped from an initial z-position of 3.8 x 106 m through the center of a planet with a radius of 8.5 x 106 m. If the mass of the planet is 48.8 x 1015 kg, measure the displacement of the ball at time t = 7 s?
