Answer:
a= 1.59 m/s² : Magnitude of the acceleration
β = 65.22° (north of east) : Direction of the acceleration
Explanation:
Conceptual analysis
We apply Newton's second law:
∑F = m*a (Formula 1)
∑F : algebraic sum of the forces in Newton (N)
m : mass in kilograms (kg)
a : acceleration in meters over second square (m/s²)
Problem development
The acceleration is presented in the direction of the resultant force applied .
Calculation of the resultant forces (R)
R= 429.5 N
We apply the formula (1) to calculate the magnitude of the acceleration(a) :
∑F = m*a , m= 270 kg
R= m*a
429.5 =270*a
a= 1.59 m/s²
Calculation of the direction of the acceleration (β)
β = 65.22° (north of east)

Explanation:
Strain energy is defined as the energy stored in a body due to deformation. The strain energy per unit volume is known as strain energy density and the area under the stress-strain curve towards the point of deformation. When the applied force is released, the whole system returns to its original shape.
Explanation:
A race car's main target is how to have rapid acceleration by scaling its speed. Acceleration of car is mostly a product of the force of the car engine.
According the newtons second law"The acceleration of body in motion depends on two main variables, the net force acting on it and the mass".
It is also written mathematically as:
F = m x a
F is the net force produced by the engine
m is the mass of the car
a is the acceleration.
Re-writing the equation:
Now Acceleration =
We can see that acceleration is directly related to increasing force but inversely proportional to the mass.
A race car needs to have a good acceleration so as to attain top speed.
The more the mass, the less the acceleration.
This is why extra weight like the seats are expunged.

It is called a Nanomaterial
Heat is added to the system.
The relation between thermal energy and temperature change in mass is given by the following expression
q = m•C•ΔT
where q is the quantity of heat transferred
m is the mass
C is the heat capacity of the material
ΔT is the temperature change
