For a lab, you place a coin on the edge of a turn table with radius of 0.5 cm, and spin at increasing speed until it slides off. You measure that the velocity when the coin slid off was 3 m/s2 . What is the coefficient of static friction between the coin and the turn table?

Freya has a mass of 14kg she is running at 1.1m/s to the left when she runs into eric, who is standing still. eric has a mass of 18kg. after the collision, they continue moving together. what is their velocity after the collision. a. 0.48 m/s to the leftb. 2.5 m/s to the leftc. 0.86 m/s to the leftd. 1.4 m/s to the left
