Answer:
39 m/s
Explanation:
Hi!
The equation of motion of the ball is:

Where y_0 is the initial horizontal position, which we will take as zero.
v_0y is the initial velocity and t is the time
To find the initial velocity we will set y(7.96s) = 0

We could determine the acceleration using this formula

Given from the question v₀ = 23 m/s, v₁ = 0 (the car stops), t = 5 s
plug in the numbers



a = -4.6
The acceleration is -4.6 m/s²
3. Coal burning
The coal releases chemicals when it is burned. So it is chemical to thermal.
