Question

A particle is fired vertically upward the speed of v=V(0.8Ve).if the radius of the earth is r then maximum height attained by the particle will be

Answer 1

A projectile is fired vertically upward from the surface of earth with a velocity Kve

A projectile is fired vertically upward from the surface of earth with a velocity of kvE, where vE is the escape velocity and k<1. Neglecting air resistance, the maximum height to which it will rise, measured from the centre of earth is (R = radius of earth)
