two balls of masses "m1" and "m2" are thrown from the tower in the horizontal direction at speeds of "u1" and "u2" respectively at the same time, which of the balls strikes the ground first??
{a}the ball thrown with greater speed
{b}the ball thrown with lesser speed
{c}the ball with greater mass
{d}the balls strike the ground simultaneously
note:for each option, briefly, say why your answer!!!!

when the balls are released , the experience gravitational force due to which acceleration of g in downward direction .
This acceleration is irrespective of mass .their instantaneous vertical position will be same before hitting ground and horizontal velocity would remain constant (no force in horizontal direction).
although they will fall apart from each other but will hit the ground at same time .
So the answer is d

The option,"{d}the balls strike the ground simultaneously" is correct as vertical component in bothcases is zero. Horizontal velocity whatever does not interfere with vertical motion, which remains same if we neglect air resistance., and air buoyancy.
