Central Force

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force between two massive objects or electrostatic forces between two charged particles. So from atoms to planets, the central forces play an important role in shaping our daily lives. One of the remarkable features of central forces is that they are conservative, i.e. the total energy of a central force system can always be expressed as a gradient of a potential energy function.

Question

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 4900 m/s. By observing the planet,
you determine its radius to be 4.48 x 10° m. You then land on
the surface and, at a place where the ground is level, launch a
small projectile with initial speed 11.6 m/s at an angle of 30.8°
above the horizontal.
