A projectile of `2 kg` has velocities `3 m//s` and `4 m//s` at two points during its flight in the uniform gravitational field of the earth. If these two velocities are `_|_` to each other then the minimum `KE` of the particle during its flight is

A projective of 2kg was velocities 3mls and 4mls at two points during its flight in the uniform gravitational field of the earth. If these two velocities are bot to each other then the minimum KE of the particle during its flight is

A projectile of mass 2kg has velocities 3m//s and 4m/s at two points during its flight in the uniform gravitational field of the earth. If these two velocities are perpendicular to each other, then the minimum kinetic enerty of the particle during its flight is
