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.
Only the speed will change because it is in motion
The x-acis of a trajectory represents its C
Answer:
so what ever one is new here
The answer is C. 35m/s because there is no direction
