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 earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
