6. A roller coaster is designed so that the car is pulled up to the top of the first hill by a chain and
pulley system. After that, however, the car coasts the rest of the way through the track, never being
pulled or pushed again until its brakes stop it. Under these conditions, what is wrong with the roller
coaster designed below?

scientific laws are the result of testing theories and proving them to be facts.

  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.
