When visiting the Italian town of Pisa, young physics student Isaac Galilei drops an apple with a weight of 2.0 N from the city's famous leaning tower. The apple falls 56 m to the ground. First question: Ignoring air resistance and other subtle effects, how long does it take the apple to fall to the ground? The apple takes s to fall to the ground.
