1sum1 plz try
consider a body projected in horizontal direction at certain heightwith velocity v
1trajectories possiblity
a)circular p)total mech energy<0
b)ellipse (not a circle) q)v=v0
(c)parabola r)v<vo
(d)hyperbola s) v>ve
t)vo<v<ve
u)v=ve
vo=orbital velocity,ve=escape velocity

24v<vo => path is ellipse with centre of earth has focus and total energy <0
v=vo => path is circle and total energy <0
vo<v<ve => path is ellipse and total energy <0
v=ve => path is parabola and total energy =0
v>ve => path is hyperbola and total energy >0
