Question

A ball, when kept on a spring attains a
certain height after it is compressed
and released For which of the
following height attained by the
ball, maximum of his energy is
required?​

Answer 1

Answer:

9 m.

• Maximum energy depends on the work done in compressing the spring which is directly proportional to the height attained by the ball after the spring is released. The gravitational potential energy is expressed as "m x g x h” and it would be the maximum for the height of 9 m.
