I need to calculate the:
1. gravity
2. weight of a physics text
3. time for an egg to drop one meter
4. gravitational force between neptune and the sun
5. tangential velocity of neptune
6. period
7. escape velocity
8. time to get there from earth in a spaceship
9. density of neptune compared to earth
I need this by November 30 (tomorrow!!). Anyone who can help, please do!! Please explain the calculations and include which equations you used, too please. Thank you so much in advance!!
All but one are simple Newtonian physics. I recommend consulting your textbook (You may need a bathroom scale for 2).
Question 8 is more interesting. I'm thinking a Hohmann Transfer Orbit. Hint--use the sun as the central point and it should work out to about one half of Neptune's orbit.
