Desde que altura debes de lanzar una canica de 50g para que adquiera una energia de 100j

204 m

Explanation:

When the marble is dropped from a certain height, its gravitational potential energy converts into kinetic energy. So the kinetic energy gained is equal to the variation of gravitational potential energy:

where

m is the mass of the marble

g = 9.8 m/s^2 is the acceleration of gravity

is the change in height

In this problem, we have

m = 50 g = 0.05 kg

Solving the formula for , we find the necessary height from which the marble should be dropped:

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
