Answer :
To determine the velocity of the roller coaster as it moves down, we use the kinematic equation which is expressed as 2gy = vf^2 - v0^2 where g is the gravitational acceleration, y is the elevation of the roller coaster, vf and vo are the final and initial velocity. We calculate as follows:
2gy = vf^2 - v0^2
Since it starts at rest, v0 is zero.
2gy = vf^2
vf = √2gy
vf = √2(9.8)(101)
vf = 44.5 m/s
Roller coaster
An elevated train track with sharp twists, steep slopes, and occasionally inversions is used in roller coasters, which are a type of amusement ride. The rides are frequently found in theme parks and amusement parks around the world. Passengers go along the track in open vehicles. One of the earliest roller coaster designs was patented in 1885 by LaMarcus Adna Thompson in connection with the Switchback Railway, which had debuted at Coney Island the year before. Shuttle roller coasters show that a coaster's track does not necessarily need to be a full circuit. The majority of roller coasters contain several cars with seating and restraints.
