A hoop rolls with constant velocity and without sliding along level ground. Its rotational kinetic energy is:a- half its translational kinetic energyb- the same as its translational kinetic energyc- twice its translational kinetic energyd- four times its translational kinetic energy

Its Rotational Kinetic Energy Is:Answera- Half Its Translational Kinetic ... As Its Translational Kinetic Energyc- Twice Its Translational Kinetic Energyd- Four ... A hoop rolls with constant velocity and without sliding along level ground. ... b- the same as its translational kinetic energy ... d- four times its translational kinetic energy Explanation:

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

  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.
