Velocity: 11.86 m/s Acceleration: 0 m/s Mass: 8255 kg Potential Energy: U = mgh= 8255kg*9.8*3m= 242,697J Kinetic Energy: KE = 1/2mv^2 = (1/2)(8255)(11.86)^2 = 580,572.499J Total Energy: U+KE = 242,697J + 580,572.499J = 823,269.499J I estimated the height of the roller coaster to be 3 meters of the ground to find the potential energy. Velocity: 16.26 m/s Acceleration: 6.644 m/s/s Mass: 8255 kg Potential Energy: U = mgh = 8255kg*9.8*5m = 404,495J Kinetic Energy: KE = 1/2mv^2 = (1/2)(8255kg)(16.26m/s)^2 = 1,091,259.82J Total Energy: U + KE = 404,495J + 1,091,259.82J = 1,495,754.82J

I estimated the mass of the roller coaster to be 8255 kg which is the same as the sidewinder. I also estimated the height of the roller coaster to be 5m which I used to find potential energy.
