A 5 kg box is lying at rest on a frictionless surface. If you push it with a constant net force of 10 N, how far will it travel
Contact [7]

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:

  • F = 10 N
  • m = 5 kg

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)
  • a = 2 m/s²

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

The trunk of a elephant may extend up to 2.2 m. It acts much like an organ pipe only open at one end when the elephant blows air
Talja [164]

Answer:

1) f = 38.63 Hz , 2)   f = 115.9 Hz

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
