Answer:
Acceleration is defined as the ratio between the change in velocity of an object and the time it takes for the object to change the velocity.
In formula, this is written as:
where
vf is the final velocity
vi is the initial velocity
t is the time it takes for the object to accelerate from u to v
Note that acceleration is a vector, so it can also be caused by a change in the direction of the velocity, not only by a change in its magnitude.

The velocity is
Henrietta is at distance from the under the window
Explanation:
From the question we are told that
The speed of Henrietta is
The height of the window from the ground is
Generally the time taken for the lunch to reach the ground assuming it fell directly under the window is
=>
=>
Generally the time taken for the lunch to reach Henrietta is mathematically represented as
Here is the time duration that elapsed after Henrietta has passed below the window the value is given as 4 s
Now
=>
Generally the distance covered by Henrietta before catching her lunch is
=>
=>
Generally the speed with which Bruce threw her lunch is mathematically represented as
