An object is thrown vertically upward with an initial kinetic energy of 4000 J from the level where its potential energy is 6000 J. When it is halfway to its highest point, its kinetic energy will be J and its potential energy will be J.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

an energy transformation flow diagram is shown

where is it ?

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
