If you are 2.0 s from being directly under a window that is 11 m above the sidewalk your standing on, and someone throws a water ballon will you get hit?
To determine if you will get hit by the water balloon, we need to calculate the horizontal distance the water balloon will travel in 2.0 seconds.
Assuming no air resistance, we can use the equations of motion to find the horizontal distance traveled by an object under constant acceleration. In this case, the only force acting horizontally on the water balloon is gravity.
The equation we can use to calculate the horizontal distance traveled is:
distance = initial velocity × time
In this scenario, the initial velocity of the water balloon in the horizontal direction is zero because it is being thrown vertically downward. Therefore, the equation becomes:
distance = 0 × time
Since the initial velocity is zero, the horizontal distance traveled by the water balloon is zero.
So, based on this calculation, if you are 2.0 seconds away from being directly under the window, the water balloon will not hit you if it is thrown vertically downwards.
However, this calculation assumes no air resistance and perfect accuracy in throwing the balloon straight down. In reality, air resistance and the angle of the throw can affect the horizontal distance the water balloon will travel.
