Questions
A particle is projected with a speed . The coefficient of friction between the particle and the hemispherical plane is m = 0.5. Then, the acceleration of the particle is
detailed solution
Correct option is B
When the particle comes with the contact of hemisphere surface, it will slide and friction will be of kinetic nature. This kinetic friction will provide tangential acceleration to the particle. Tangential acceleration of the particle,at=μmgm=μg=g2←.Normal acceleration of the particle,an=v2R=gRR=g↑. Net acceleration of the particle, anet=at2+an2=g24+g2=5g2.Talk to our academic expert!
