If velocity vector of a particle just before making an inelastic impact with a smooth horizontal x -y plane surface with coefficient of restitution 0.2 is `(15hat i-20hat j-50hat k)m/s` with z-axis being vertically upwards.The velocity vector of the particle just after collision (in m/s) will be?

Velocity vector of a particle just before making an inelastic impact with horizontal smooth surface with coefficient of restitution 0.2 is (3hati - 10 hatj - 50 hatk) m/s with z-axis being vertically upwards. Velocity of the particle 1s after collision (in m/s) will be:-

A smooth sphere is moving on a horizontal surface with velocity vector 3hat(i) + hat(j) immediately before it hits a vertical wall. The wall is parallel to the vector hat(j) and the coefficient of restitution between the wall and sphere is (1)/(3) . The velocity vector of the sphere after it hits the wall is :-

What is the cosine of the angle which the vector sqrt(2)hat i+hat j+hat k makes with y-axis?

What is the cosine of the angle which the vector sqrt(2)hat i+hat j+hat k makes with y-axis?

A particle strikes a smooth horizontal surface at an angle of 45^(@) with a velocity of 100m//s and rebounds. If the coefficient of restitution between the floor and the particle is 0.57 then the angle which the velocity of the particle after it rebounds will make with the floor is
