so the answer should be weight=416.46N?

OPS! thank you for noticing that!

I don't see how my value for g of the planet is wrong though...

so is it just g of the planet which I found to be 489.95N/kg, and times that by 85kg (which is the mass of the astronaut)? If I do that I get weight=force due to gravity=41646.12N

Homework Statement A planet's mean distance from the sun is 2.00x10^11 m. Determine the planet's orbital period. Use information found in textbook. Homework Equations So I use the following equations: R=h+Rs T=2∏√(R3/GxMs) From the textbook I got the following values...

does h= 2618294.399m seem like the correct answer?

thank you so much for your help and patience! along with everyone else who helped, it is greatly appreciated!

So now I solve for a=3g=29.4m/s2 and then plug that into my acceleration equation from earlier and solve for the radius which should give me R=85m ... Does this seem reasonable?

Oh ops! I knew that... so its 3mg right?

net force on Snoopy would be 5mg?

the m is messing me up and i don't know why

his weight would be Fg=m*g=9.8m/s2 pulling downwards? FN=4*m*a? pulling upwards?

There's Fg pulling downwards and 4FN pushing up?

is the a=g/4?

You keep saying in terms on m and g, but I thought m canceled out? Sorry its hard for me to picture it without seeing it in front of me
