The speed of a moving bullet can be deter- mined by allowing the bullet to pass through two rotating paper disks mounted a distance 69 cm apart on the same axle. From the angular displacement 30.5 of the two bul- let holes in the disks and the rotational speed 1104 rev/min of the disks, we can determine the speed of the bullet. 30.5 1 104 rev/ min -69 cm What is the speed of the bullet? Answer in units of m/s.An amusement park ride consists of a rotat- ing circular platform 9.09 m in diameter from which 10 kg seats are suspended at the end of 1.97 m massless chains. When the system ro- tates, the chains make an angle of 31.3" with the vertical. The acceleration of gravity is 9.8 m/s. d What is the speed of each seat? Answer in units of m/s. part 2 of 2 If a child of mass 43.7 kg sits in a seat. what is the tension in the chain (for the same angle)? Answer in units of N
