It takes a time t = 0.53 s for a record to revolve on a record player once. A particular point on the record moves past the needle at a speed of v, = 1.04 m/s. Randomized Variables t = 0.53 s Vy = 1.04 m/s Part (a) What is the radius at which the needle is in contact with the record in m? Part (b) What is the tangential speed v, of a point on the record that is at r2= 0.05 m in m/s? v2 =

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force betwe…
