a 1,500 kg roller coaster is traveling at 32 m/s as it goes over a 6 meter tall hill. what is the kinetic energy of the roller coaster?

768000 joule

Explanation:

As we know that

K.E = 0.5 x mv2

Here m stands for mass, the measure of how much matter is in an object, and v stands for the velocity of the object, or the rate at which the object changes its position.

putting the value we get

K.E = 0.5 x (1500KG)(32 m/s)2

K.E =768000 J

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
