(a) Calculate the speed in m/s of a satellite in an orbit 850 km above the Earth's surface. m/s (b) Suppose a loose rivet is in an orbit of the same radius that intersects the satellite's orbit at an angle of 90° relative to Earth. What is the velocity in m/s of the rivet relative to the satellite just before striking it? (Enter the magnitude.) m/s (c) Given the rivet is 4.00 mm in size, how long in seconds will its collision with the satellite last? (Assume the rivet is flattened like a pancake on the surface of the satellite during the collision.)

How would you solve this problem?? Thank you so much!!!

7) Assume that we have a distant Star-Planet system with no other planets and the Star is the same as the Sun and the planet is the same as the Earth. (This is called an "Earth analog" or "Earth twin".) The masses and orbits are the same, except you can assume a perfect circular orbit. a. Calculate the equation for the orbital velocity of a planet on a circular orbit. To do this use the equation for average speed: distance=rate * time. In a circular orbit, the speed (not the velocity!) is always the same, so can use a time that is one full orbital period (i.e., 1 year). What is the distance that a planet on a circular orbit traverses in this time? Calculate the speed of the Earth twin in meters/second.

12. Escape Velocity To escape Earth's gravitational field, a rocket must be launched with an initial velocity called the escape velocity. A rocket launched from the surface of Earth has velocity v (in miles per second) given by V = 2GM Tº + v² - 2GM R where vo is the initial velocity, r is the distance from the rocket to the center of Earth, G is the gravitational constant, M is the mass of Earth, and R is the radius of Earth (approximately 4000 miles). V= a. Find the value of vo for which you obtain an infinite limit for r as v approaches zero. This value of vo is the escape velocity for Earth. 192,000 T b. A rocket launched from the surface of the moon has velocity v (in miles per second) given by V = 1920 T +v-48 + - 2.17. Find the escape velocity for the moon. c. A rocket launched from the surface of a planet has velocity v (in miles per second) given by 10,600 T + v² - 6.99. Find the escape velocity for this planet. Is the mass of this planet larger or smaller than that of Earth?…
