Let's say 2 planets are 364,496,829 m apart. If planet 1 is 2.9x1020 kg and planet 2 is 4.0x1019 kg, what is the force of gravity between the two planets?

Aperson walks first at a constant speed of 4.89 m/s along a straight line from point a to point b and then back along the line from b to a at a constant speed of 2.95 m/s. what is the average speed over the entire trip?
