Escape velocity. We suppose that r = -gR^2/r^2. Suppose that a rocket is fired straight up, from the surface of the Earth with a velocity that is exactly half of the escape velocity. How high will the rocket go?

A 1.2ft diameter ball is thrown onto a rough surface, such that it has a velocity of 6ft/s and a backspin angular velocity of w. If it is to stop backspinning at the same instant as the velocity is 0, the backspin w in rad/s is what? HINT: The answer is independent of the mass and coefficient of friction.
a. 17.8
b. 22.0
c. 2

Write the simplest possible one-dimensional "molecular dynamics code" for two particles. I used matlab, so i need matlab code for molecular dynamics or velocity verlet algorithm code. I need to determine x1, x2 and v1, v2 in different time steps.
I have the following 15 values for x1, x2 and v1,v2 in graphs:
M = 1.0
d

Two spheres each of mass m, can slide freely on a frictionless, horizontal surface. Sphere A is moving at a speed Vo=16 ft/s when it strikes sphere B which is at rest and the impact causes sphere B to break into two pieces, each of mass m/2 Knowing that 0.7s after the collision one piece reaches point C and 0.9s after the collis

If a planet has a mass of 9.42 x 1024 kg and a radius of 5.47 x 106 meters, to the nearest m/s what is its escape velocity?
If the mass is increased by a factor of 2, what is the new escape velocity?
If the radius is decreased by a factor of 0.22, what is its new escape velocity?

A satellite of mass 830 kg orbits a planet of unknown mass at a distance of 29100 km from the planet's center. The orbital velocity of the satellite is 14200 m/s.
* What is the mass of the planet?
* How much would potential energy (PE) and kinetic energy (KE) of this satellite change as the satellite moved from a circular

Find the linear velocity of a point on the edge of a drum rotating 52 times per minute. The diameter of the wheel is 16.0in. Please show me all the steps thank you
