Problem: A roller coaster starts out being pulled to the top of a 17m high hill, where it is dropped ( so it starts out not moving at the top of the hill.) it then goes all the way down at a steep angle before going around a curve, then moving back up to a height of 9m off the ground.
Part I: How fast will it be traveling at the point?
Please show work I think I have the answer just not positive. Thanks.
