A roller coaster has an initial speed of 9.50 m/s at the top of the first hill, which is 44.00 m above the ground. Neglecting friction, what will be the speed of the roller coaster at the top of the next hill, which is 26.00 m above the ground?
The total energy possessed by the object (the roller coaster) is a constant or it is conserved in the whole process.
<br>The initial energy is KE1 + PE1 = (1/2)m V^2 ...
