A bucket of water rotates in a vertical circular orbit with a radius of 1.6 m. What should be the minimum speed (in m / s) of the bucket so that water does not spill at the upper point of the orbit?
You are exploring a distant planet. When your spaceship is in a circular orbit at a distance of 630 km above the planet's surface, the ship's orbital speed is 5500 m/s. By observing the planet, you determine its radius to be 4.48×106m. You then land on the surface and, at a place where the ground is level, launch a small projectile with initial speed 12.6 m/s at an angle of 30.8∘ above the horizontal.
If resistance due to the planet's atmosphere is negligible, what is the horizontal range of the projectile?
Given that earth has a radius of 6.4X10^6 m at its equator, what is the linear velocity at earths surface? V=?

- You are a visitor aboard the New International Space Station, which is in a circular orbit around the Earth with an orbital speed of ?o=2.45 km/s�o=2.45 km/s . The station is equipped with a high velocity projectile launcher, which can be used to launch small projectiles in various directions at high speeds. Most of the time, the projectiles either enter new orbits around the Earth or eventually fall down and hit the Earth. However, as you know from your physics courses at the Academy, projectiles launched with a sufficiently great initial speed can travel away from the Earth indefinitely, always slowing down but never falling back to Earth. With what minimum total speed, relative to the Earth, would projectiles need to be launched from the station in order to "escape" in this way? For reference, recall that the radius of the Earth is ?E=6370000 m�E=6370000 m, the mass of the Earth is ?E=5.98×1024 kg�E=5.98×1024 kg , the acceleration due to gravity on the surface of the Earth is ?=9.81…arrow_forwardIf there is a net force on a particle in uniform circular motion, why doesn’t the particle’s speed change?arrow_forwardYou wish to put a 1000.0 kg satellite into a circular orbit above the earth's surface with a period of 300.0min.
