Answer:
5 ft/s²
Explanation:
u = Initial velocity = 100 ft/s
v = Final velocity = 0
s = Displacement = 1000 ft
a = Acceleration
From equation of motion


The airplane's deceleration is 5 ft/s² or 1.524 m/s²
Answer:
42.86m
Explanation:
The first thing we should keep in mind is that the watermelon moves with uniform acceleracion equal to gravity (9.81m / s ^ 2)
A body that moves with constant acceleration means that it moves in "a uniformly accelerated motion", which means that if the velocity is plotted with respect to time we will find a line and its slope will be the value of the acceleration, it determines how much it changes the speed with respect to time.
When performing a mathematical demonstration, it is found that the equations that define this movement are as follows.

where
Vf=29m/s= final speed
Vo= initial speed=0m/S
g=gravity=9.81m/s^2
Y= distance traveled(m)
solving

the distance traveled by watermelon is 42.86m
