Answer:
V=15.3 m/s
Explanation:
To solve this problem, we have to use the energy conservation theorem:

the elastic potencial energy is given by:

The work is defined as:

this work is negative because is opposite to the movement.
The gravitational potencial energy at 2.5 m aboves is given by:

the gravitational potential energy at the ground and the kinetic energy at the begining are 0.

Answer:
0.24 ? I hope that was the answer you were looking for.

b) 120÷10
c) answer A÷Answer B.
sure on first two, not so sure on C.
A longitudinal wave transports energy through the medium without permanently transporting matter.
Hope this helps :D
