Given:
The mass of the car is m = 1725 kg
The initial velocity of the car is
[tex]v_i=\text{ 3 m/s}[/tex]The final velocity of the car is
[tex]v_f=\text{ 12 m/s}[/tex]The time is t = 4.4 s
To find the applied force.
Explanation:
The force can be calculated by the formula
[tex]F=\text{ ma}[/tex]Here, a is the acceleration.
The acceleration can be calculated as
[tex]\begin{gathered} a=\frac{v_f-v_i}{t} \\ =\frac{12-3}{4.4} \\ =2.045\text{ m/s}^2 \end{gathered}[/tex]On substituting the values, the force applied will be
[tex]\begin{gathered} F=ma \\ =1725\times2.045 \\ =3527.625\text{ N} \end{gathered}[/tex]Thus, the applied force is 3527.625 N
