A pendulum reaches a maximum height of h above the equilibrium position as it oscillates. Assuming friction and air resistance are negligible, what is true about the total energy of the Earth-pendulum system as the pendulum oscillates?

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

this could be newton#'s law of cooling. the cooling curve is exponential

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
