Answer:
Explanation:
From the question we are told that
Radius of vertical r= 8m
Force exerted by passengers is 1/4 of weight
Generally the net force acting on top of the roller coaster is give to be
where
Generally the net force is given to be 
Mathematical we can now derive V
Therefore the speed of the roller coaster is given ton be
Answer:
