Answer :
Answer:
Due to energy loss while collision ball will not reach to same height while if there is no energy loss then in that case ball will reach to same height
Explanation:
Explanation:
As we know that initially ball is held at height h = 40 cm
So here we can say that kinetic energy of the ball is zero and potential energy is given as
U = mgHU=mgH
now when strike with the ground then its its fraction of kinetic energy is lost in form of other energies
So the ball will left rebound with smaller
When the ball strikes the surface of the earth, the some of the kinetic energy could be converted into heat and sound energy. Due to the some energy loss, the ball could not bonce back to the original height from which height it falls. Explanation: At 40 cm, the ball is in rest position.
