Please can you solve this question in physics quickly
IA frictionless roller coaster starts from rest 25 m above the
ground. (a) What's its speed when it reaches the ground?
(b) Upon reaching the ground, the track goes into a vertical, cir-
cular loop. Find the maximum loop radius such that the car will
maintain contact with the track at the top.
No friction -> mechanical energy is conserved
