Problem
When two identical smooth spheres collide obliquely on a frictionless horizontal surface, which component of each sphere’s velocity remains unchanged by the impact?
(a) Normal component measured along the line joining the centres
(b) Radial component measured from the centre of mass of the two–sphere system
(c) Tangential component measured along the common tangent at the point of contact
(d) Magnitude of the velocity (speed) of each sphere
