A projectile is fired with initial velocity v at an angle , has timeof descent T. If the initial velocity be reduced to half at the same angle of projection then Time of descent becomes
Time of descent is time taken in moving downward
so As we know time taken to reach highest point from the ground(time of ascent) = time taken to come back to ground from highest point(time of descent) = T
velovity is reduced to half and angle is same implies that new time of descent will be
