- A ball is on the end of a string. The ball is being swung in a vertical circle at a constant speed. The length of the string is 1.25 m. The mass of the ball is 2.10 kg. The maximum tension the string can withstand is 61.0 N. What is the max speed of the ball without breaking the string when the ball is at the top of the circle (point a)?At a circus, a stunt rider is going to do a "Loop-de-Loop". The radius of the circular part of the track is 8.13 m. The mass of the motorcycle and the rider is 318. kg. What is the minimum speed the motorcycle must have to just make it around the loop without falling?A 1,669 kg automobile is moving at a maximum speed of 27 m/s on a level circular track of radius 88 m. What is the coefficient of friction?
- Pablo ties a small stone to the end of a rope and is spun in a horizontal circle. If the mass of the stone is 0.40 kg and that of the rope is 0.75 m. What is the largest speed that the stone can have if the rope will break when the tension is 260 N?A 51 kg object is experiencing a net force of 250 N while traveling in a circle of radius 1.5 m. What is its velocity?The passengers in a roller coaster feel 42 % heavier than their true weight as the car goes through a loop with a 30 m radius of curvature. What is the car's speed at the bottom of the loop? Use g = 10 N/kg. Hint: How heavy some one feels is another name for normal force. The problem therefore tells you the normal force. If you know weight and normal force, you can determine centripetal acceleration. You can substitute a value for mass if you wish.
- NASA uses a machine often called the "vomit comet" to mimic the effects of low gravity in space during astronaut training. The machine moves in circular arcs at a speed of v = 214 m/s. What is the radius the pilot must fly to create weightlessness as they go around the top of the circular arc? Give your answer in meters.A ball is on the end of a string. The ball is being swung in a vertical circle at a constant speed.The length of the string is 1.30 m. The mass of the ball is 2.10 kg. The maximum tension the string can withstand before breaking is 54.0 N.What is the maximum speed of the ball without the string breaking when the ball is at the top of the circle (Point A in the figure)?A car of mass 622 kg is driving around a curve with a circular arc of radius 20 m. If the car drives at a speed of 12 m/s, what is the minimum value of the coefficient of friction between the car's tires and the road that will keep the car on the road?
