If you solve that you don't get 14.8, your def missing something here!

Nevermind i figured this one out :p

[b]1. Design a "bungee jump" apparatus for adults. A bungee jumper falls from a high platform with two elastic cords tied to the ankles. The jumper falls freely for a while, with the cords slack. Then the jumper falls an additional distance with the cords increasingly tense. Assume that you have...

How would i then answer this part: What is the kinetic energy of the reaction products (helium nucleus plus photon)? I know how to solve the rest of the problem other than those two parts.

Thanks a lot that gave me the right answer.

[b]1.This is all the given information: In a fusion reaction, the nuclei of two atoms join to form a single atom of a different element. In such a reaction, a fraction of the rest energy of the original atoms is converted to kinetic energy of the reaction products. A fusion reaction that...

Thanks that helped a lot!

GMm/ R^2 ?

Do i use F = (mv^2)/r ?

[b]1. A satellite of mass 8000 kg orbits the Earth in a circular orbit of radius of 9.5 106 m (this is above the Earth's atmosphere).The mass of the Earth is 6.0 1024 kg. What is the speed of the satellite? [b]2. Pf = pi+Fnet + delta t [b]3. the only thing i knew to try was...
