5. A flying swings ride rotates with a speed of 5 m/s. If the average person has a mass of 70 kg and the chair has a mass of 5 kg, and the chair makes an angle of 36' with the vertical. What is the tension in the string holding the chair? (assume there is only one string) What is the radius of the circle the person is traveling in? (927.05 N, 3.44 m ) 6. Suppose a string was attached to a fan as it was on creating an angle of 35 to the vertical. On the end of the string was a little ball. How much tension is in the string if the ball has a mass of 3 kg and moves with a radius of 1.5 m? What is the speed of the ball? (36.6 N, 3.24 m/s) 7. A 0.15 kg ball is being swung in a vertical circle at the end of a 1.1 m long cord as shown. If the ball is moving at 4 m/s at the top of the circle, what is the tension in the cord? What is the tension in the cord at the bottom of the circle if the speed of the ball is double what it is at the top? (.6818 N, 10.227 N) Find the apparent weight of a 70 kg person going 20 m/s at the bottom of a coaster with a radius of curvature of 50 m. How many times his actual weight is this? (1.8 times)
