Two bodies were thrown simultaneously from the same point, one straight up, and the other, at an angle of 30degree to the horizontal. The initial speed of each body is 20 m/s . Neglecting air resistance, the distance between the bodies at t=1.2 later Class 11 Vector Relative motion

 

When the velocity makes an angle 30° with the horizontal, the kinetic energy of the body will be K/2 K/3 2K/3 3K/4 Class 11 Vector Projectile Motion
