In the figure the man hanging upside down is holding a partner who weighs 535 N. Assume that the partner moves on a circle that has a radius of 6.50 m. At a swinging speed of 3.75 m/s, what force must the man apply to his partner in the straight-down position?

During a circus act, one performer swings upside down hanging from a trapeze holding another, also upside down, performer by the legs. If the upward force on the lower performer is three times her weight, how much does each of the bones (the femurs) in her upper legs stretch (in m)? You may assume each is equivalent to a uniform rod 35.0 cm long and 1.80 cm in radius. Her mass is 51.5 kg. Assume Young's modulus for bone under...

During a circus act, one performer swings upside down hanging from a trapeze while holding another performer, also upside-down, by the calves. The legs (femurs) of the lower performer undergo deformation due to the upward force from the upper performer. If the upward force on the lower performer's legs is 3mg (three times her weight), how much do the bones (the femurs) in her upper legs stretch in meters? You may assume each bone is equivalent to a uniform rod...

1. John (who is 95 kg) drives his car over an absurdly large half-circle speedbump with a radius of 5 meters. Given that his normal weight is 930 N and his apparent weight at the top of the speed-bump was 246 N, how fast did he drive over the speed bump? 2. When working in circular motion problems, what do we define as always being the positive direction? 3. When in circular motion, the net force points in what direction?...

ECE Review Worksheet 1 AP Physics Mr. Marrash 1. A space traveler weighs 980 N on Earth. What will the traveler weight on another planet whose radius is 3 times that of the Earth and whose mass is also 9 times that of the Earth. Do not use any numerical values of the universal gravitational constant G, the mass of Earth, or the radius of Earth to get your answer. 2. Two skaters, a man and a woman, are standing...
