An object on a number line moved from x=12m to x=124m and moved back to x=98m .The time interval for all the motion was 10s . What was the average velocity?

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

i don't understand. explain it clearly
