A hockey player traps a fast ball with deft use of the stick. In terms of kinetic energy and work done, why is it more difficult to stop a faster ball that is otherwise identical?

graph question answered .. you think better when you are relaxed and happy

  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.
