Answer: 11.36 m

Step-by-step explanation:

Given

Mass of roller coaster is m=1200 kg

Initial speed of roller coaster is v=15 m/s

Energy at bottom and at the top is same i.e.

$\Rightarrow (1)/(2)mv^2=mgh\\\\\Rightarrow (1)/(2)* 1200* 15^2=1200* 9.8* h\\\\\Rightarrow h=(15^2)/(2* 9.8)\\\\\Rightarrow h=11.36\ m$

Thus, the highest point reach by the roller coaster is 11.36 m
