A ball is thrown vertically upward from the ground. It crosses a point at the height of 25 m twice at an interval of 4 seconds. The ball was thrown with the velocity of
The interval between object pass the same point is 4 sec.
That means in 2 sec, object reaches the top and in next 2 sec, it again reaches the same point.
By the info given, we can find the velocity of that point by using : v=u+(-gt)
0= u - 10×2
u = 20
Then the velocity at 25m is 20m/sec.
so the initial velocity is
-v2 = u2 + (-2gh)400 = u2 - 2x 10 x 25u2 = 900 => u = 30 m/s

When combining with nonmetallic atoms, metallic atoms generally will Lose electrons and forms cations.
As the ionization energy of te metals are very low, so they can easily lose electrons and form positively charged ion called cations.
