If a rock weighing 2,200 n is dropped from a height of 15 m, what is its ke just before it hits the ground? remember, weight is measured in newtons (n), and is equal to mass times gravity. a. 0 j b. 2,224 j c. 147 j d. 33,000 j

This is a question conservation of energy. That is;
Potential energy = Kinetic energy

mgh = 1/2*mv^2 = KE

Therefore,
KE = mgh = (2200/9.81)*9.81*15 = 2200*15 = 33000 J

The correct answer is D.

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.
