Question

derive an expression of minimum speed of vehicle in well of death
​

Answer 1

Answer:

Explanation:

in the death well , the moter cycle rider dont fall because centripetal force is balanced by the normal components and weight.

now we calculate the total force acting on the rider to balance the centripetal force.

At top the velocity of rider is minimum , so we say v=0 at top

so normal component become zero

F(net)=centripetal force

f+mg=centripetal force

here f= normal component

at top f=0

so

mg=centripetal force

mg=mv^2/r

v=(rg)^1/2

v=(25*10)^1/2

v=15.8m/s
