A smooth circular table is surrounded by a rim whose interior is vertical . A ball is projected along the table from a point on the rim in a direction making an angle theta to the radius through the point and returns to the point of projection after two impacts . If e be the coefficient of restitution, then

A cylindrical hall has a horizontal smooth floor. A ball is projected along the floor from A point on the wall in a direction making an angle theta with the radius through the point the ball returns bak to the initial point after two impacts with the wall. if the coefficient of restitution is e than tan^(2)theta will be

A smooth hoop lie as on a smooth horizontal table and is fixed. A particle is projected on the table form a point A on the inner circumference of the hoop at angle theta with radius vector . If e be the coefficient of restitution and the particle returns to the point of projection after two successive impacts. The final angle theta' made by velocity vector with radius of hoop is

A particle is projected vertically upward with velocity u from a point A , when it returns to the point of projection .

A particle is projected vertically upward with velocity u from a point A , when it returns to the point of projection .

A ball of mass m is projected from the ground with an initial velocity u making an angle of theta with the vertical. What is the change in velocity between the point of projection and the highest point ?
