A is at rest initially and B is moving with velocity v along x-axis. After collision B has a velocity v/2​ in a direction perpendicular to the original direction. The mass A moves after collision in the direction.

Two sphere A and B of masses m1​ and m2​ respectively collide. A is at rest initially and B is moving with velocity v along x-axis. After collision B has a velocity v/2​ in a direction perpendicular to the original direction. The mass A moves after collision in the direction.

A bullet of mass 10g moving horizontally with a velocity of 400 m/s strikes a wood block of mass 2 kg which is suspended by a light inextensible string of length 5 m. As a result A missile is fired for maximum range with an initial velocity of 20m/s. If g = 10m/s2 the range of the missile is
