Frame of reference

In physics, a frame of reference is a coordinate system used to specify either the position or the orientation or velocity of a body. The origin of the coordinate acts as a reference point for measuring the position or relative motion of a body. The coordinate system can be a cartesian coordinate, cylindrical coordinate, or a polar coordinate.

Question

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.

You are now in 20 years old. You are disappointed with the current situation. So, you decide to leave to the future of Earth. You plan a space journey for 5 years(go in 2.5 years and back in 2.5 years.) with a constant speed relative to Earth.

There is a galactic, royal wedding in El Candrea. Maria Isabela, the princess of andalusia prima maxima, is riding a diamond-studded, pink spacetime motorcycle whose maximum speed is 5x10^2 km/s. The religious princess started her speed at about 5x10^1 km/s and she is to supposed to travel 1.78 x 10^4 km at a straight distance in about 60 seconds to reach the wedding before the galactic church closes. The princess accelerated until her max speed was reached. She then maintains the aforementioned speed till she reached the wedding gates. To reach the church before it closes, what should be her minimum constant acceleration? a. 8.30 km/s^2, b. 7.50 km/s^2, c. 5.29 km/s^2, or d. 6.95 km/s^2
