Step-by-step explanation:

3X + 12 = 22 - X

3X + X = 22 - 12

4X = 10

X = 5/2

5/2 is also the length of the diagonadiagonal

Answer:

• A vehicle of mass 20 kg is moving with a velocity of 4 m/s .
• If it is applied on the vehicle so that the vehicle of 1 m/s after travelling a distance of 20 m.

• What is the magnitude of the force.

First, we have to find the acceleration :-

Given :

• Initial Velocity (u) = 4 m/s
• Final Velocity (v) = 1 m/s
• Distance Covered (s) = 20 m

According to the question by using the formula we get,

[tex]\implies \sf\boxed{\bold{v^2 =\: u^2 + 2as}}\\[/tex]

[tex]\implies \sf (1)^2 =\: (4)^2 + 2a \times 20\\[/tex]

[tex]\implies \sf (1 \times 1) =\: (4 \times 4) + 40a\\[/tex]

[tex]\implies \sf 1 =\: 16 + 40a\\[/tex]

[tex]\implies \sf 1 - 16 =\: 40a\\[/tex]

[tex]\implies \sf - 15 =\: 40a\\[/tex]

[tex]\implies \sf \dfrac{- 15}{40} =\: a\\[/tex]

[tex]\implies \sf - 0.375 =\: a\\[/tex]

[tex]\implies \sf\bold{a =\: - 0.375\: m/s^2}\\[/tex]

Hence, the acceleration is - 0.375 m/s² .

Now, we have to find the magnitude of the force :-

Given :

• Mass (m) = 20 kg
• Acceleration (a) = - 0.375 m/s²

According to the question by using the formula we get,

[tex]\implies \sf\boxed{\bold{Force =\: Mass \times Acceleration}}\\[/tex]

[tex]\implies \sf Force =\: 20 \times (- 0.375)\\[/tex]

[tex]\implies \sf Force =\: - 7.5\\[/tex]

[tex]\implies \sf\bold{\underline{Force =\: - 7.5\: N}}\\[/tex]

[tex]\therefore[/tex] The magnitude of the force is - 7.5 N .
