im not quite sure i understood exactly what you were referring to when it comes to acceleration of the object. the question in its entirety is here. a projectile is shot directly away from Earth's surface. Neglect the rotation of Earth. What multiple of Earth's radius Re gives the radial...

i had this assignment last year. was probably one of the more fun projects i had in my calculus class. I made stewie from family guy. everyone recognized it right away, i was so proud. haha. good luck, i had mostly trial and error. friend of mine (beign much smarter) figure out his stuff on...

I have a 3 part question, and I have managed to get 2 of the three parts, but I can not figure out the 3rd for the life of me. A projectile is shot directly away from Earth's surface. Neglect the rotation of Earth. (C) What is the least initial mechanical energy required at launch if the...

i forgot to mention that my problem was the same, only with numerical values. ill write it out for your sake here: a spherical hollow inside a lead sphere of radius R = 4.00 cm; the surface of the hollow passes through the center of the sphere and "touches" the right side of the sphere. The...

well the way i was going to go about it was to determine the density of the one large hollow sphere without the circle taking out of it, then find the mass of the hollow that is taken out of it. Then i was going to find the attraction between the hollowed out mass (minus the sphere taken out)...

hi, sorry to revive an old thread, but i was wondering if someone could explain in more depth the answer to this problem. I've been struggling with it for a while, I guess I am not the strongest in physics. If anyone could help it would be much appreciated.
