Question

A body is projected horizontally from a point above the  ground and motion of the body is described by the equation $$x=2t$$,$$y=5t2$$     where x, and y  are horizontal and vertical coordinates in metre after time t. The initial  velocity of the body will be

Infinity Learn · Accepted Answer

The horizontal  velocity of the projectile remains constant throughout the journey. Since the  body is projected horizontally, the initial velocity will be same as the  horizontal velocity at any point.  Since, $$x=2t$$,$$dxdt=2$$     ∴     Horizontal velocity $$=2m/s$$∴     Initial velocity $$=2m/s$$

A body is projected horizontally from a point above the ground and motion of the body is described by the equation $x = 2 t, y = 5 t^{2}$ where x, and y are horizontal and vertical coordinates in metre after time t. The initial velocity of the body will be
