A particle of mass m and speed v strikes a stationery particle(of unknown mass) in a glancing collision. Is it possible for the incident particle to have a final (nonzero) velocity at right angles to its incident velocity? If so, under what condition? please Help.

Definitely possible...the other mass which is at rest before collision has to be of infinite mass. The angle of collision w.r.t the direction of motion depends on elasticity of collision...for perfectly elastic collision the glancing angle would be 45 degrees. There are infinite no of solutions possible.

Thank You So much for the answer, but if you prove it  by equation it will be perfect.
