A satellite orbiting Mars (6.39x1023kg) experiences a gravitational field of 2.40N/kg. How far from Mars is the satellite orbiting?

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.

What is the orbital period of a spacecraft in a low orbit near the surface of mars? the radius of mars is 3.4×106m.

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
