1.) potential energy
2.)potential and kinetic
3.)The roller coaster car has the most kinetic energy at point X i know this because the car is moving and kinetic energy has the power to move or change things therefore point X is when the roller coaster car has the most energy.

Answer:
The veolcity of the 7 kilogram body is approximately 0.14 meters per second
Explanation:
Here we have to use the conservation of linear momentum for the bodies asumming the force of the spring an internal force on the system formed by the two blocks. So the change on linear momentum (
) has to be zero.
The final momentum 
is the sum of the final momentum of each block, and initial linear momentum 
is zero because the blocks were initially at rest, so:
It's important to note that the linear momentum is a vector quantity so the direction of the velocities are important, assuming positive the velocity of the 5 kilogram body
The speed is 0.14 meters per second and the negative sign means the direction is opposite of the 5 kg body velocity.
