If the mass of a spaceship is approximately 5x10^9 kg, how much mass must be converted into kinetic energy to accelerate it from rest to one-tenth the speed of light? How much mass would be required to decelerate the spaceship to rest in space? Recall that there is no friction in space.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
