The force is always equal to the product of mass and acceleration. The mass of the object is 2218.7 Kg.
An object travels 7.5 m/s toward the west.
Under the influence of a constant net force of 5.2 kN, it comes to rest in 3.2 s.
Now,
The initial velocity of the object is 7.5 m/s.
The final velocity of the object is 0 m/s.
The object comes to the rest position in 3.2 seconds.
The formula for finding the acceleration of the object is mentioned below:
[tex]v=u+at\\0=7.5+a \times 3.2\\a= -2.34375\;\rm m/s^2[/tex]
The formula for finding the force is mentioned below:
[tex]F=ma\\-5.2 \times 10^3=m \times 2.34375\\m=2218.7 \ \;kg[/tex]
Hence, the mass of the object is 2218.7 Kg.
