Aunt Gloria is cooling off an apple pie in her kitchen window when it is bumped and falls! If the window is 3.5m above the ground, what will be the velocity of the pie when it reaches the ground?

8.29 (m/s)

Explanation:

1. potential energy before the falling is:

where 'm' is mass of the pie; 'g' - is 9.81 N/kg; 'h' - is height of the window (h=3.5 m).

2. cinetic energy of the pie when it is reaching the ground is:

where 'm' is the mass of the pie; 'v' - the velocity of the pie when it is reaching the ground.

3. according to the condition

then

and

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

  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.
