A 4.0 kg mass is moving along the x axis. The potential energy curve as a function of position is shown. The kinetic energy of the object at the origin is 12 J. The system is conservative. There is no friction. (a) What will be the kinetic energy at 2.0 m along the x axis?

(b) What will be the speed of the object at 6.0 m along the x axis?

PLEASE help​

less than one you can't create energy

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

there are no components of a physical goal mentioned on the list of choices that you've provided.
