You are in a spaceship far outside our solar system. inside your spaceship there is not gravity and no air (and therefore no air resistance). if you toss a ball across the spaceship, how do newton's laws predict its motion will change as it moves?

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
