A ball is thrown horizontally and at the same time another ball is dropped from the top of a tower - with same velocity (i) will both the balls hit the ground with the same velocity, (ii) will both the balls reach the ground at the same time ?


#2

(i) When the balls hits the ground; their vertical velocities are equal. However the horizontal velocities will be different. Hence the resultant velocities of the two balls are different, so the balls would hit the ground with different velocities. 1 (ii)Both the balls would reach the ground at the same time because their initial vertical velocities, acceleration and distance covered are all equal.
