A heavy particle is projected from a point on the horizontal at an angle 60 degree with the horizontal with a speed of 10 M per second then the radius of the curvature of its path at the instant of crossing the same horizontal is.

As the particle moves from its initial position to its final position, its vertical velocity decreases at the rate of 9.8 m/s each second. During this time its horizontal velocity is constant. Let’s determine the vertical and horizontal components of the initial velocity. 

Vertical = 10 x sin 60=5

, Horizontal = 10 x cos 60 = 5 m/s 

In a projectile horizontally components  of velocity remains constant.

...     10cos60°=Vcos30°...     V=10cos60°sec30°=10×
