A ball is thrown horizontally from the top of a building. What will be its vertical displacement from the top of building 2.0 seconds after it leaves your hands?
A) 4.9 m
B) 9.8 m
C) 19.6 m
D) 40.2 m
E) 52.4 m

The vertical displacement of the ball can be calculated using the formula d = (1/2)gt^2, where d is the displacement, g is the acceleration due to gravity (9.8 m/s^2), and t is the time. Plugging in the values, we get: 
d = (1/2)(9.8 m/s^2)(2.0 s)^2
d = 19.6 m
Therefore, the vertical displacement of the ball 2.0 seconds after it leaves your hands is 19.6 meters.
