Question

a car of mass 800 kg moving on a circular track of radius 40 m if the coefficient of friction is 0.5 then the maximum velocity with which the car is​

Answer 1

tan @ = v^2 / rg

Putting tan @ = coefficient of friction

v = sqrt ( coefficient of static friction * r * g)

v = sqrt (0.5 * 40 * 9.8 )

v = sqrt ( 196)

v = 14 m/s
