The Burj Khalifa in Dubai is the world’s tallest build at 828 m. According to FIFA regulations, a soccer ball must exhibit a restitution ratio greater than 0.82 at a temperature of −20◦C. What is the total vertical distance a soccer ball would travel if dropped from the Burj Khalifa? You may ignore the size of the ball and assume only vertical motion. BONUS: If the restitution ratio was instead 0.99, what is the minimum height you could drop the...
