2N left Brutus is pulling the bone with 2 more Newtons of force than Lassie
Answer:
h=4r
Explanation:
To solve the problem it is necessary to apply the energy conservation equations for the roller coaster.
The energy conservation equations warn that:
Where,
Kinetic Energy
Potential Energy
Equating,
Re-arrange for V,
For balance of forces, according to the announcement, those who are on a roller coaster can withstand up to a maximum of 9g.
Therefore, considering the centripede speed and the speed of the fall, we obtain that,
The centripetal acceleration is given by the equation
Where
V = Tangencial velocity
r = Radius
Then replacing in the equation of Force,
Therefore the maximum height of the incline if the cars starts from the rest is 4 times the raidus of the inclination
