Two balls of different masses are thrown vertically upwards with the same speed . They pass through the point of projection in their downward motion with the same speed ( Neglect air resistance ).

Explanation

When the two balls are thrown vertically upwards with the same speed `u` then their final speed `v` at the point of projection is `v^(2) - u^(2) = 2 xx gxx s`
Here , `s = 0 `
`:. v = u ` for both the cases
