Answer: 1200 kg
Explanation: Taking into account the Newton's second law, the mass of the vehicle is 1200 kg.
In first place, acceleration in a body occurs when a force acts on a body. There are two factors that influence the acceleration of an object: the net force acting on it and the mass of the body.
Newton's second law states that this force will change the speed of an object because the speed and / or direction will change. These changes in velocity are called acceleration.
So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object.
Mathematically, Newton's second law is expressed as:
F= m×a
where:
F = Force [N]
m = Mass [kg]
a = Acceleration [m/s²]
In this case, you know:
F= 1800 N
m= ?
a= 1.5 m/s²
Replacing:
1800 N= m× 1.5 m/s²
Solving:
m= 1800 N÷1.5 m/s²
m= 1200 kg
Finally, the mass of the vehicle is 1200 kg.
Ok the answer for this question would be B. Hope this helps.

Angular displacement of the cd is 3.25 rev
Explanation:
The question is incomplete. It is not given what is the maximum angular velocity of the cd.
Here we are going to assume that the maximum angular velocity is:
The motion of the cd is an accelerated angular motion, therefore we can use the following suvat equation:
where:
is the angular displacement of the cd during the time interval t
is the initial angular velocity of the cd
is the final angular velocity
Here we have:
t = 1.36 s
(assuming the cd starts from rest)
Therefore, the angular displacement of the cd during this time is:
And since 
, we can convert into number of revolutions completed:
