The distance traveled by the box over the first 4 s is 16 m.
To solve the problem above, First, we apply newton's Fundamental equation of force.
<h3 /><h3>Newton's fundamental equation of force:</h3>
F = ma...................... Equation 1
Where
- F = Force
- m = mass of the box
- a = acceleration
make "a " the subject of the equation
a = F/m...................... Equation 2
From the question,
Given:
Substitute these values into equation 2
a = 10/5
a = 2 m/s²
Finally, we use the equation of motion to calculate the distance it will travel over the given period of time.
<h3><u>Equation of motion</u></h3>
s = ut+at²/2........................... Equation 3
Where:
- s = total distance traveled
- t = time
- u = initial velocity
Given:
- t = 4 s
- u = 0 m/s (at rest)
Substitute these values into equation 3
- s = 0(4)+(2×4²)/2
- s = 0+32/2
- s = 16 m
Hence, the distance traveled by the box over the first 4 s is 16 m

Explanation:
The elephant's trunk can be approximated by a tube with a closed end, in pipes the closed ends correspond to nodes and the open ends to antinodes or bellies.
The expression for the wavelengths of this system is
4L = n λ
n = 1, 3, 5, 7 ...
also let's use the relationship between frequency and wavelength and wave speed
v = λ f
f = v / λ
f = v n / 4L
f = v / 4L n
1) the fundamental frequency occurs for n = 1
f = 340/4 2.2 1
f = 38.63 Hz
2) The first harmonic
n = 3
f = 340/4 2.2 3
f = 115.9 Hz
