“to predict the speed that a coaster will reach before it is ever placed on the track. ... When coaster goes up by height h then its gravitational potential energy increases by the amount m.g.h where m = mass of coaster, h = height of coaster and g = gravitational acceleration due to Earth”
<h2>
Answer:</h2>
The distance will be 1800 m
<h2>
Explanation</h2>
As in question
Time = 15 min
Time = 15 x 60 sec = 900 sec
Speed = 2 m/s
We know that
So, the answer is 1800 m
