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 4.48×106 m. you then land on the surface and, at a place where the ground is level, launch a small projectile with initial speed 14.6 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?

Explanation:

As we know that the orbital speed is given as

here we know that

v = 5500 m/s

now we have

now acceleration due to gravity of planet is given as

now range of the projectile on the surface of planet is given as

for this one it would be d bump/forearm pass

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
