A body moving along the x-axis is subject to a force repelling it from the origin, given by F = kx.

i.) Find the potential energy function U(x) for the motion and write down
the conservation of energy condition.

ii.) Describe the motion of the system and show that this is the kind of
motion we would expect near a point of unstable equilibrium.

answer: i think he can see forward ten seconds and move forward ten seconds but giorno can undo his actions with ger.

explanation:

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

not too sure thinking all accelerations are pointed down
