Questions
A particle moving horizontally with a velocity u strikes a fixed frictionless sphere at a height R/2 above the center of sphere. After striking the sphere, velocity of particle changes to vertically upward .If R be the radius of sphere, the maximum height attained by the particle with respect to center of sphere is
detailed solution
Correct option is A
Since the force of contact will be only normal force, ∴The velocity of the particle along the tangent will be conserved during the collisionUsin30=Vsin60V=U3Maximum height from centre=R2+V22g=R2+U26gTalk to our academic expert!
