Galileo's assistant drops a cannonball from the top of the Leaning Tower of Pisa. The ball falls from rest in a straight, vertical line under the influence of gravity alone until it hits the ground. It takes 3.37s to hit the ground. = 9.8ms-2. Take the magnitude of the acceleration due to gravity to be g = Give numerical answers to two significant figures. (a) Calculate the height of the Leaning Tower, and the final speed that the ball reaches before hitting the ground. (b) Draw a graph of the velocity v (in metres per second) of the ball against the time t (in seconds), from the time at which the ball is dropped until the instant before it hits the ground.
