A motor cyclist loops a vertical loop of diameter 50 m , without dropping down even at uppermost point . What is the minimum speed at lowest and highest points of the loop ?

Text Solution

Verified by Experts

Here ` 50 // 2 = 25 m `
` upsilon L = sqrt(5 r g )= sqrt( 5 xx 25 xx 9.8 ) = 35 m // s `
` upsilon H = sqrt (rg )= sqrt (25 xx 9.8 ) = 15 . 65 m // s ` .
