CIRCULAR MOTION PRACTICE PROBLEMS. 1. In aviation, a "standard turn" for a level flight of a propeller-type plane is one in which the plane makes a complete circular turn in 2.00 minutes. If the speed of the plane is 170 m/s, a. What is the radius of the circle? 2 …
1. A race car makes one lap around a track of radius 50 m in 9.0 s. a) What is the average velocity? b) What was the car’s centripetal acceleration? 2. Normie Neutron swings a rubber ball attached to a string over his head in a horizontal, circular path. The piece of string is 1.5 m long and the ball makes 120 complete turns each minute.

On the figures below, draw and label all the forces exerted on the ball when it is at points P and Q, respectively. b. Derive an expression for v min the minimum speed the ball can have at point Z without leaving the circular path. c.
MYP Physics Circular Motion Practice Problems. Solutions. relatively high speeds. As part of their lab, Tyler and Maria estimate that the riders travel through a circle with a radius of 6.5 m and make one turn every 5.8 seconds. Determine the speed …
Physics Circular Motion Solutions Part I 1. If the radius of the path of a body in uniform circular motion is doubled and the speed is kept the same the force needed must be (a) half as great as before. (b) the same as before. (c) twice as large as before. (d) four times the size as before. Answer (a). Since speed is constant not frequency. 2.
2012年12月11日 · Circular Motion Problems – ANSWERS 1. An 8.0 g cork is swung in a horizontal circle with a radius of 35 cm. It makes 30 revolutions in 12 seconds. What is the tension in the string? (Assume the string is nearly horizontal) T=time/revolutions=0.4 s Period is the time per revolution F=ma Write down N2L F tension = mv
