Kingda Ka is a steel roller coaster located in Jackson, New Jersey. The max speed is 128 miles per hour. You have to be 4’7 to ride on it. 1,400 people go on it an hour and it opened May 21, 2005. It’s the tallest and fastest roller coaster in North America. You go 0-128 miles per hour in 3.5 short seconds. It’s 90 degrees straight up and there is no time to think or do anything. It’s a U shaped roller coaster and you have to be brave to go on it. My sister and brother went on it, but I was too scared to. When you get to the top you go right back down, you barely have time to see the beautiful view. The next time I go, I am so going on it.
