Dylan puts two magnetic toy trains very close to each other on a track. What will happen next, and
-hy?
a
The trains will not move because the magnets are not touching.
b
The trains will move closer to each other because the magnetic force will pull the trains
together
с
The trains will move away from each other because the magnetic force will push the trains
apart.
d
The trains will move away from each other because the magnets are not touching.

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
