A spaceship with a mass of 5.30 104 kg is traveling at 5.75 103 m/s relative to a space station. What mass will the ship have after it fires its engines in order to reach a speed of 8.39 103 m/s

Mass needed to fire is

Explanation:

Mass of the spaceship

Initial velocity of the spaceship

Final velocity of the spaceship

Take exhaust velocity

The velocity of the spaceship in the  space is

Mass needed to fire is

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
