W1=200rpm*2pi/60=20.9rad/s
w2=200rpm-.10(200rpm)=180rpm
180rpm*2pi/60=18.8rad/s
a=(18.8-20.9)/10= -.21rad/s^2
I=1/2(28)(.15)^2
I=.315kg*m^2
Torque= -.21(.315)=.06615 N*m
Friction force= -.06615/.15=-.441 N
Normal force of man=.441/.2= 2.205 N
Final answer: -2.205 N

The answer to this question is two violins, a viola and a cello
The string quartet is one of the earliest form of musical ensembles in history. This form of ensembles was brought to recognition by the Austrian composer Joseph Haydn<span>, with his works in the 1750s establishing the genre and this form is still considered one of the hardest ensembles because each player has to cover a lot of parts within a session.</span>
(C)150 J, because the initial and final energy must be the same in an isolated system
Oh yea.. the Law of Conservation of energy states that energy stays the same throughout a system XD bet

Answer:
<h3>Newton's 2nd law states acceleration is proportional to the net force acting on an object. The net force is the vector sum of all the forces applied to the object. ... In this case the acceleration (slowing down) of the puck is proportional to the amount of friction.</h3>
