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...

1.) A 1.7-kg falcon catches and holds onto a 0.675-kg dove from behind in midair. What is their final speed, in meters per second, after impact if the falcon’s speed is initially 27 m/s and the dove’s speed is 7.5 m/s in the same direction? 2.) a.) A bowling ball of mass mb = 3.7 kg is rolled down the lane with a velocity of v1 = 2.8 m/s. It strikes a single remaining pin mp = 0.92 kg head...
Two skaters gliding on ice run into each other head-on. If the two skaters hold onto each other and continue to move as a unit after the collision
Part III: Solve the following problems Two skaters gliding on ice run into each other head-on. If the two skaters hold onto each other and continue to move as a unit after the collision, what will be their resultant velocity? Skater A has a velocity of 5 m/s and a mass of 65 kg. Skater B has a velocity of 6 m/s and a mass of 60 kg.

Two carts on an air track are moving toward each other. One has mass 2.0 kg and velocity -0.90 m/s, and the other has mass 3.0 kg but unknown speed. They collide in a totally inelastic collision, and move with velocity +1.2 m/s after the collision. What was the initial speed of the second cart (in m/s)?

In outer space, far from any other influences, two rocks collide and bounce off each other. All motion is along the x axis. Rock A has a mass of 3 kg, an initial velocity of 〈40,0,0〉m/s, and a final velocity of 〈16,0,0〉m/s. Rock B has a mass of 6kg and an initial velocity of 〈−20, 0, 0〉 m/s. (a) What is the final 3-D velocity vector (not speed!) of Rock B? (b) What is the change in the total kinetic...

Two skydivers are holding on to each other while falling straight down at a common terminal speed of 57.10 m/s. Suddenly, they push away from each other. Immediately after separation, the first skydiver, who has a mass my of 83.80 kg, has a velocity v1 with the following components ("straight down" corresponds to the positive z-axis). 01.x = 4.930 m/s 01.y = 4.750 m/s 01,2 = 57.10 m/s What are the x- and y-components of the velocity U2 of the...

Two skydivers are holding on to each other while falling straight down at a common terminal speed of 63.10 m/s. Suddenly, they push away from each other. Immediately after separation, the first skydiver (who has a mass of 89.30 kg) has the following velocity components (with "straight down" corresponding to the positive z-axis): v_1, x = 4.930 m/s v_1, y = 4.750 m/s v_1, z = 63.10 m/s What are the x- and y-components of the velocity of the second...

Page 13 9. A 49.8-kg athlete running at 4.54 m/s suddenly jumps onto a stationary playground merry-go-round at a distance 1.45 m from the axis of rotation of the merry-go-round. She is traveling tangential to the edge of the merry-go-round just before jumping on. The moment of inertia about its axis of rotation is 625 kg m2 and very little friction at its rotation axis. What is the angular speed of the merry-go-round just after she has jumped onto it?...

Question 8. (15 Marks) Two gliders move toward each other on a frictionless track (Figure O8a). Glider A has a mass of 0.50 kg, and glider B has a mass of 0.30 kg: both gliders move with an initial speed of 2.0 m/s. (a) Assume that after the collision, glider B moves away with a final velocity of +2.0 m/s (Figure Q8c). What is the final velocity of A? (b) Assume that after the collision, the two gliders stick together...
