Q. A ball A of mass 0.1 kg moving with velocity 6 m/s collides directly with a bal B of mass 0.2 kg at
rest. Calculate their common velocity if both balls
move oft together. If A had rebounded with a
velocity of 2 m/s in the opposite direction after
collision,
what would be the new velocty of B?

heat the gas and measure the pressure

  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.
