Question

A body of mass 100 gm is projected vertically up with a velocity of 10m/s and another body of same mass is projected vertically down with same velocity from the top of a tower of height 20m. Calculate the K.E of each ball on reaching the ground? (Take g=10m/s²).​

Answer 1

Answer:

5J and 7J

Explanation:

We know kinetic energy is 1/2 mv2 so we can solve this and answer is 5 J for first ball and 7J for second ball
