A man standing on the edge of a cliff throws a stone straight up with initial speed (u) and then throws another stone straight down with same initial speed and from the same position. Find the ratio of the speeds. The stones would have attained when they hit ground at the base of the cliff.

Statement-I : When the direction of motion of a particle moving in a circular path is reversed the direction of radial acceleration still remains the same (at the given point). Statement-II : Particle revolves on circular path in any direction such as clockwise or anticlockwise the direction of radius accelerationis always towards the centre of the circular path.

A hunter is riding an elephant of height 4 m moving in straight line with uniform speed of 2m//sec . A deer running with a speed V in front at a distance of 4sqrt(5) moving perpendicular to the direction of motion of the elephant. If hunter can throw his spear with a speed of 10m//sec . relative to the elephant, then at what angle theta to it's direction of motion must he throw his spear horizontally for a successful hit. Find also the speed 'V' of the deer.
