Mass does not make a roller coaster go faster but it does make it harder to slow down. This is why amusement parks test roller coasters with dummies filled with water. The water dummies increase the mass of the train making it harder for the resistance forces to slow it down so it's less likely to get stuck.
Theme park designer Brian Morrow explained that rollercoasters get faster throughout the day because they need to warm up earlier in the day, like a car. He told Mental Floss: A coaster running in the morning could run slower when cooler. “The wheels are not as warm, the bearings are warming up.
People with high blood pressure and/or heart conditions are warned not to ride roller coasters because of the way they tax the cardiovascular system. The adrenaline rush that roller coasters give you causes a rapid spike in your heart rate and blood pressure.
