Complete Question
A system consists of a disk of mass 2.0 kg and radius 50 cm upon which is mounted an annular cylinder of mass 1.0 kg with inner radius 20 cm and outer radius 30 cm (see below). The system rotates about an axis through the center of the disk and annular cylinder at 10 rev/s.
(a) What is the moment of inertia of the system
(b) What is its rotational kinetic energy? axis 50 cm 30 cm 20 cm
Answer:
a)
b)
Explanation:
From the question we are told that:
Mass
Disk Radius
Mass of annular cylinder
Inner Radius of cylinder
Outer Radius of cylinder
Angular Velocity
Generally the equation for moment of inertia is mathematically given by
Generally the equation for Rotational Kinetic Energy is mathematically given by
Children with low self efficacy will take a longer time to achieve their targets whereas those with high self effficacy will be more likely to find success easily
The answer is A.
p=m/v
p= 240/60
p= 4 g/cm^3
Under constant acceleration, we have average velocity over a time interval of duration satisfying
where are the plane's initial position and velocity (respectively) and are the plane's position and velocity (respectively) after 9.00 seconds. So
