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.
Answer:
Explanation:
Notation
represent the tensile strength for the Kevlar 49 fibers
represent the tensile strength for the epoxy resin
79% by volume is made of Kevlar 49 fibers
The rest 100-79=21% is made of epoxy resin
Tensile strength is a "measurement of the force required to pull something such as rope, wire, or a structural beam to the point where it breaks". Can be defined as "the maximum amount of tensile stress that it can take before failure".
For this case we need to use a basis of calculus since we don't know the total volume but we can assume a reference value on order to make the calculations.
If we assume a total volume of 
we can do the follwoing balance:
We can replace the values given:
So then the strength of the composite material is :
Scalar quantities have only a magnitude. So the answer is scalar quantities.
