Assuming it starts at rest, the roller coaster only has potential energy at the top of the hill, which is
When it reaches the bottom, its potential energy will have converted to kinetic energy,
where 
is its velocity at that point. By the law of conservation of energy, assuming no loss of energy due to other sources (e.g. sound, heat), we have
The approximate value for the distance between the two points is <span>3.162277663.16227766</span>.
<span><span>√10</span>≈<span>3.16227766

The conservation of momentum P states that the amount of momentum remains constant when there are not external forces.
We don't have external forces, so:
Where:
- mb is the mass of the bowling ball
- mp the mass of the pin
the initial velocities of the bowling ball and the pin.
the final velocities of the bowling ball and the pin.
Solving for v0b:
<h2>R/ The original velocity of the ball was 5.71 m/s.</h2>
