Your spaceship lands on an unknown planet. To decide the characteristics of this planet, you drop a 1.00kg wrench from 3.50m above the ground and gauge that it hits the ground 0.811 Slater. You also do enough surveying to decide that the circumference of the planet is 6.28×10 4km.
Determine what is the mass of the planet, in kilograms?
Express the planet’s mass in terms of the earth’s mass.
Achilles is lurking inside a high wall that defends an ancient city. If Achilles stands up against the inside surface of the wall he will be safe. If he begins to walk away from the wall, find at what distance from it will the archer be able to hit..
