Can anyone help me with these 2 ? 1.) A cd with a diameter of 12 cm, speeds up from 0 to 4 rev/s in 3s. What is the tangential acceleration of a point on the outer rim of the disk at the moment when angular speed is a.) 2 rev/s b.) 3 rev/s 2.) A fisherman reels in a fish and turns the spool on the reel at a rate of 3 revolutions per second. If the radius of the reel is 3.7 cm, what is the linear speed of the fishing line as it is reeled in ?
