Aball is sitting on the top of a table. the ball has 100 j of potential energy (pe). it falls off the table and falls straight down to the ground.

at the instant it reaches the ground, how much kinetic energy (ke) does the ball have?

a.
9.8 j

b.
50 j

c.
100 j

d.
0 j

At the instant, it just reaches the ground, no energy has been lost as the Friction, so Energy would be same.

In short, Your Answer would be Option C) 100 J

Hope this helps!

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
