Question

derive an expression for the minimum speed of the vehicle which derive in horizontal circle (well of death )
​

Answer 1

Answer:

When the motorcyclist is at the highest point of the death - well, the normal reaction R on the motorcyclist by the ceiling of the chamber acts downwards. His weight mg also act downward

Here v is the speed of the motorcyclist and m is the mass of does not fall down. The minimum speed required to perform a vertical loop is given by equation (1) when R=0.

Therefore,
