In a circus trapeze act, two acrobats actually fly through the air and grab on to each other, then together grab a swinging bar. One acrobat, with a mass of 70 kg, is moving at 3.9 m/s at an angle of 15° above the horizontal and the other, with a mass of 41 kg, is approaching her with a speed of 3.9 m/s at an angle of 12° above the horizontal. What is the direction and speed of the acrobats right after they grab on to each other? Let the positive x−axis be in the horizontal direction and assume the first acrobat has positive velocity components in the positive x− and y−directions.

15. Two acrobats flying through the air grab and hold onto each other in midair as part of a circus act. One acrobat has a mass of 60 kg and has a horizontal velocity of 5 m/s just before the grab. Another acrobat has a mass of 50 kg and has a horizontal velocity of -3 m/s just before the grab. Their horizontal velocity immediately after they grab onto each other is: A) 1.4 m/s B) 4.1 m/s c) 2.0...

A circus act consists of a performer (a "human cannonball") being launched from a cannon into a net at the other end of the stage. The performer (mass 60 kg) leaves the cannon at a speed of 25 m/s at an angle of 30o above horizontal. She comes out of the cannon at a height of 2 meters above the ground and lands in the net at a horizontal distance of 45 meters away from the launch point. 1. How...

swings from a trapeze, projects herself at an angle of 53 ∘, and is
supposed to be caught by Joe Bob, whose hands are 6.1 m above and

§A favorite circus act is the “human cannonball,” in which a person is shot from a long barrel. §Before the Italian Zacchini brothers invented the compressed air powered cannon to shoot human cannonballs in the 1920s, the Englishman George Farini used a spring-loaded cannon to do the same since the 1870s. §Suppose we want to recreate the spring-loaded human cannonball act with a spring inside of a barrel. §Suppose the barrel is 4.00 m long, and you have room to...

The Flying Physics Brothers, Stu and Lou, end their act by both being shot out of cannons. They fly through the air and land at the same height they left the cannons. Assume air resistance can be neglected Stu's initial speed is 15.91 m/s and Lou's initial speed is 20.28 m/s. Stu leaves the cannon at an angle of 64.8° and Lou leaves the cannon at an angle of 35.1°. As usual, the angles are measured upwards from the positive-x...

Two pucks are on an air table. Puck A has a mass of 0.025 kg and an initial velocity of 5.5 m/s in the positive x-direction. Puck B of mass 0.05 kg is at rest. Puck A collides with puck B. Puck A moves at an angle of 65° above the x -axis and puck B at an angle of 37 degrees below the x -axis. What is the final speed of puck A? and the final speed of puck...

** 45. Two cannons are mounted as shown in the drawing and rigged to fire simultaneously. They are used in a circus act in which two clowns serve as human cannonballs. The clowns are fired toward each other and collide at a height of 1.00 m above the muzzles of the cannons. Clown A is launched at a 75.0° angle, with a speed of 9.00 m/s. The horizontal separation between the clowns as they leave the cannons is 6.00 m....
