After a long day of physics labs, you get home and want to unwind with some music. You pick out your favorite record and put it on the turntable, then press play. The 12-inch diameter record is brought to a rotational speed of 33.3 revolutions per minute ) 4; U Question 1 2 pts Express the radius of the record in cm Question 2 2 pts Express the rotational speed in rad/s v j,,,,,,,,, Question 5 Question 6 Time Running: Hide Time Attempt due: Nov 4 at 11:59pm 29 Minutes, 51 Seconds 1/ courses/ 32972/quizzes/ 35852 i [take Question 3 2 pts If it takes 0.66 seconds to bring the record from rest to its final velocity, what is its angular acceleration? Question 4 2 pts The mass of the record is 150g, and the mass of the metal disk it rests on in the turntable is 500g. Both have the same radius and rotate about the same axis. What is the moment of inertia of the record+disk together? They can each be thought of as very thin (but solid) cylinders. Express your answer with units of kg m"2. Question 5 2 pts An ant inadvertently crawls onto the record before it starts spinning. If it sits 4cm from the center of the record. what is its linear velocity as the record spins? Express your answer in units of m/s
