Help on physics/astronomy problem...?
You want to send a spacecraft from Earth to Mars [P(Mars)=1.88 yrs; a(Mars) = 1.52 AU]
Note:. You can use a sketch to show the relative positions of Earth and Mars when you launch the spacecraft.
1. What is the period of the spacecraft's orbit?
2. How long will it take the spacecraft to get to Mars?

Mary weighs 100 pounds. Compared to what she weighs now, how much would she weigh if: The radius of the Earth were .5 its present value?

The second I can answer quickly...
.5 the radius = 1/8th the volume... assuming mass follows, 1/8 mass. Gravity is proportional to mass, Mary weighs 12.5 lbs

Basic Hohmann transfer orbit one-way travel time is on the order of nine months. Earth departure point will be near periastron; Mars arrival point will be near apoastron.
