Answer:
The scope of physics is quite vast and covers an enormous range of magnitude of physical quantities like mass, length, time, energy etc.
The scope is divided into two sections, where on one side it studies about phenomena at a very small microscopic level involving and analyzing electrons, protons, and neutrons.
net force = 30 N
mass = 8.16 kg
acceleration = 3.68 m/s²
<h3>Further explanation</h3>
Given
80 N force applied
mass of object = 10 kg
Friction force = 50 N
Required
Net force
mass
acceleration
Solution
Net force = force applied(to the right) - friction force(to the left)
Net force = 80 - 50 = 30 N
Gravitational force(downward) : F = mg
m = F : g
m = 80 : 9.8
m = 8.16 kg
a = F net / m
a = 30 / 8.16
a = 3.68 m/s²
Answer:
Explanation:
First we convert 2 cycles/s to angular velocity knowing that each circle has an angle of 2π
Then we calculate the moment of inertia of the cylindrical shell, assuming there's no mass inside the wheel (only at the rim):
So the kinetic energy of this is
