1-An object is tied to a chord in Spohn in a circle of radius 1.3 3 m about a vertical axis edit speed of 5m/s. it will experience both a centripetal and a gravitational force. calculate the angle the cord makes relative to the horizontal.
2-a 300 KG canon fires a 4 KG ball. If the kinetic energy of the ball is 1.6x10^5J what is the kinetic energy of the cannon at the moment after the ball leaves a barrel?
