Answer:
Newton's second law
Explanation:
Mathematically, Newton's second law can be written as
where
F is the net force on the particle
m is its mass
a is the acceleration
This can also be rewritten as
which means that the acceleration is directly proportional to the force and inversely proportional to the mass. If the net force is non-zero, it means that the particle has a non-zero acceleration, therefore its velocity is changing (it can be changing either in magnitude, if the force has same direction as the velocity, or also in direction, if the force has a different direction).

Answer:
The magnitude of angular acceleration is .
Explanation:
Given that,
Initial angular velocity,
When it switched off, it comes o rest,
Number of revolution,
We need to find the magnitude of angular acceleration. It can be calculated using third equation of rotational kinematics as :
So, the magnitude of angular acceleration is . Hence, this is the required solution.
Answer:
2.59 m
Explanation:
Coordinates of origin = (0, 0)
Coordinates of Point p where the fly reach = (2.3 m, 1.2 m)
Use the distance formula of coordinates to find the distance between the origin and the point P.
d = 2.59 m
Thus, the distance between the origin and the point P is 2.59 m.
