Answer:
The mass of the truck is 11,000 Kg.
Step-by-step explanation:
Mechanical Force
According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:
F = m.a
Where a is the acceleration of the object.
It's given a truck travels at a constant acceleration of
when a net force of F=39,600 N is applied.
To find the mass of the truck, solve the equation for m:


Operating:
m = 11,000 Kg
The mass of the truck is 11,000 Kg.
