A particle of mass `m` strikes on ground with angle of incidence `45^(@)`. If coefficient of restitution, `e=(1)/(sqrt(2))`, find the velociy after impact and angle of reflection.

A particle of mass m is strikes on ground at an angle of incidence 30^(@) with initial speed of 5 m/s . Calculate (i) its velocity after impact (ii) angle of reflection . Given that the coefficient of restitution is 1/(sqrt(3))

A ball of mass m hits a floor with a speed v making an angle of incidence theta=45^(@) with the normal to the floor, if the coefficeint of restitution is e=(1)/(sqrt(2)) , find the angle of reflection.

A particle of mass M strikes a wall at an angle of incidence 60^(@) with velocity V elastically Then the change in momentum is

A ball of a mass m hits the floor with as speed v making an angle of incidence theta with the normal. The coefficient of restitution is e. Find the speed of the reflected ball and the angle of reflection of the ball.
