Suppose you are navigating a spacecraft far from other objects. the mass of the spacecraft is 2.6 × 104 kg (about 26 tons). the rocket engines are shut off, and you're coasting along with a constant velocity of < 0, 20, 0> km/s. as you pass the location < 7, 4, 0> km you briefly fire side thruster rockets, so that your spacecraft experiences a net force of < 5 × 105, 0, 0> n for 24.5 s. the ejected gases have a mass that is small compared to the mass of the spacecraft. you then continue coasting with the rocket engines turned off. where are you an hour later? (think about what approximations or simplifying assumptions you made in your analysis. also think about the choice of system: what are the surroundings that exert external forces on your system? )\

56 will be the answer all you do is divide 104 to 26 then divide 2.6

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

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
