An object of mass m attached to a spring of force constant k oscillates with simple harmonic motion. the maximum displacement from equilibrium is a and the total mechanical energy of the system is e. what is the object's velocity when its potential energy is 2/3e?

As we know that total energy of SHM is always constant

so here we know that

total energy = Kinetic energy + potential energy

so here we have

potential energy = 2/3E

so we will have kinetic energy as

now we have

now for the speed of the block

by solving above equation we have

the answer is mosques. they are an important part of islamic culture.
