The leaning tower of Pisa is about 56 meters tall. A ball released from the top takes 3.4 seconds to reach the ground. The final velocity of the ball before it hits the ground is 33 meters/second. Assuming that the ball experienced a constant acceleration throughout this descent, calculate the magnitude of the acceleration.

If it is indeed released with no initial velocity and air resistance is negligible, you can use v(t) formula:
v(t)=u+a×t
33=0+3.4a
a=333.4=9.705m/s2
