A 0.66 kg ball is moving wih a speed of 100 m//s . The associated wavelength will be.

A bullet of mass 10 g is fired from a gun of mass 1 kg with recoil velocity of gun 5 m/s. The muzzle velocity will be

A canon of mass M is mounted on an east west frictionless railway track. The barrel of cannon faces the north east direction at an angle of 45^(@) with the vertical. The canon fires a shot of mass M with a speed V relative to the barrel.

A cannon of mass 1000 kg located at the base of an inclined plane fires a shell of mass 50 kg in horizontal direction with velocity 180 km//h . The angle of inclination of the inclined plane with the horizontal is 45^(@) . The coefficient of friction between the cannon and inclined plane is 0.5 . The maximum height, in metre, to which the cannon can ascend the inclined plane as a result of recoil is
