Yes, of course! by it's definition the potential energy is an energy that particle have in order to obtain kinetic energy. Or simply an energy to make some movement.

It helps reduce the amount of carbon emissions released into the air
<span>An electrostatic precipitator is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding(slowing down) the flow of gases through the unit.

a device for removing small particles, as of smoke, dust, or oil, from a gas, as air, by passing the gas first through an electrically charged screen that gives a charge to the particles, then between two charged plates where the particles are attracted to one <span>surface.

initial height of the pole vaulter = 4.2 m
height of the pole vaulter just before it touch the pad = 80 cm
so the total displacement of pole vaulter just before he will touch the pad = 4.2 - 0.80 = 3.4 m
now by kinematics
now after this he will come to rest after compressing the pad by 50 cm
so again we can use kinematics to find its acceleration
so here its acceleration will be - 66.64 m/s^2
