A ball of mass 5 kg is dropped from a tower of height 2 m. what is its kinetic energy half way down?

Dear Student ,
Here the ball is dropped from 2 m .The half way point is when it has moved through 1 m .By the equation of motion , we can write that ,v2-u2=2ghv2=2×10×1=20 m2/s2K.E=12mv2=12×5×20=50 J
