Question

2 kg ball is dropped from a height of 10 m find its kinetic energy just before hitting the ground. in above case find the velocity of a ball just before hitting the ground​

Answer 1

Answer:

Mass of the Body = 10 kg. Height = 10 m. Acceleration due to gravity = 9.8 m/s2. Using the Formula,Potential Energy = mgh = 10 × 9.8

Answer 2

Answer:

1/2mv square

1/2*10*2square

100 square =100*100=1000
