Answer:
2
Explanation:
got it right on e d g e n u i t y 2020
Potential energy is mass * gravity * height. (m*g*h). 350 = 17*9.8*h <--350 is its energy, 17kg is its mass, and 9.8 is gravity's acceleration on the object. We now just need to solve for h. h = 350/(17 * 9.8) = 2.1 meters, which, when rounded to the nearest whole meter, is 2 meters.The shelf is 2 meters high.
