Newton's second law we can find the acceleration of the ship is
a = 0.074 m / s²
Given parameters
To find
Newton's second law states that the force varies linearly with the mass and acceleration of the body
∑ F = m a
The bold indicate vectors, where F is the sum of the forces, m the masses and the acceleration
The force is a vector magnitude, therefore it must be solved for each axis of a coordinate system, in the exerted of inclined ramps the coordinate system used has the x-axis in the direction of the ramp and the y-axis perpendicular to it, see attached. In this cordinate system the weight of the body must be decomposed.
cos 5 = W_y / W
sin 5 = Wₓ / W
W_y = W cos 5
Wₓ = W sin 5
Let's solve Newton's second law for each axis
Y axis
N - W_y = 0
N = W_y = mg cos 5
X axis
Wₓ - fr = m a (1)
Friction force is the macroscopic result of contact interactions between two bodies and is described for solids by the expression
fr = μ N
fr = μ mg cos 5
we substitute in equation 1
mg sin 5 - μ m g cos 5 = m a
a = g (sin 5 - μ cos 5)
let's calculate
a = 9.8 (sin 5 - 0.08 cos 5)
a = 0.073 m / s²
In conclusion using Newton's second law we can find the acceleration of the ship is
a = 0.073 m / s²

Answer:
The correct option is (c).
Explanation:
Given that,
The energy of a photon is,
We need to tell the color of this light. We know that, the energy of a photon is given by :
Where
c is the speed of light
The wavelength of yellow light is approx 580 nm. Hence, we can say that this photon corresponds to yellow light.
Answer:
A) The resultant force is 43.4 [N]
B) The movement of the heavy crate is going to the right and in the negative direction on the y-axis
Explanation:
We need to make a sketch of the different forces acting on the heavy crate.
In the attached image we can see the forces and the sum of the vector with their respective angles.
Forces in the X-axis
Forces in the y-axis
Using the Pythagorean theorem
The movement of the heavy crate is going to the right and in the negative direction on the y-axis, this can be easily seen in the graphical sum of vectors.
