- A giant swing at an amusement park consists of a 365-kg uniform arm 10.0 m long, with two seats of negligible mass connected at the lower end of the arm (Fig. P8.53). (a) How far from the upper end is the center of mass of the arm? (b) The gravitational potential energy of the arm is the same as if all its mass were concentrated at the center of mass. If the arm is raised through a 45.0 angle, find the gravitational potential energy, where the zero level is taken to be 10.0 m below the axis, (c) The arm drops from rest from the position described in part (b). Find the gravitational potential energy of the system when it reaches the vertical orientation. (d) Find the speed of the seats at the bottom of the swing.arrow_forwardThree runaway train cars are moving on a frictionless, horizontal track in a railroad yard as shown in Figure P11.73. The first car, with mass m1 = 1.50 103 kg, is moving to the right with speed v1 = 10.0 m /s; the second car, with mass m2 = 2.50 103 kg, is moving to the left with speed v2 = 5.00 m/s, and the third car, with mass m3 = 1.20 103 kg, is moving to the left with speed v3 = 8.00 m /s. The three railroad cars collide at the same instant and couple, forming a train of three cars. a. What is the final velocity of the train cars immediately after the collision? b. Would the answer to part (a) change if the three cars did not collide at the same instant? Explain. FIGURE P11.73arrow_forwardTwo objects are connected by a light string passing over a light, frictionless pulley as shown in Figure P7.7. The object of mass m1 = 5.00 kg is released from rest at a height h = 4.00 m above the table. Using the isolated system model, (a) determine the speed of the object of mass m2 = 3.00 kg just as the 5.00-kg object hits the table and (b) find the maximum height above the table to which the 3.00-kg object rises.arrow_forward
- Two gliders are set in motion on a horizontal air track. A spring of force constant k is attached to the back end of the second glider. As shown in Figure P8.48, the first glider, of mass m1, moves to the right with speed v1, and the second glider, of mass m2, moves more slowly to the right with speed v2. When m1 collides with the spring attached to m2, the spring compresses by a distance xmax, and the gliders then move apart again. In terms of v1, v2, m1, m2, and k, find (a) the speed rat maximum compression, (b) the maximum compression xmax, and (c) the velocity of each glider after m1 has lost contact with the spring.arrow_forwardA block of mass m1 = 4.00 kg initially at rest on top of a frictionless, horizontal table is attached by a lightweight string to a second block of mass m2 = 3.00 kg hanging vertically from the edge of the table and a distance h = 0.450 m above the floor (Fig. P8.77). If the edge of the table is assumed to be frictionless, what is the speed with which the first block leaves the edge of the table?arrow_forwardAs shown in Figure P8.20, a bullet of mass m and speed v passes completely through a pendulum bob of mass M. The bullet emerges with a speed of v/2. The pendulum bob is suspended by a stiff rod (not a string) of length , and negligible mass. What is the minimum value of v such that the pendulum bob will barely swing through a complete vertical circle? Figure P8.20arrow_forward
- You hold a slingshot at arms length, pull the light elastic band back to your chin, and release it to launch a pebble horizontally with speed 200 cm/s. With the same procedure, you fire a bean with speed 600 cm/s. What is the ratio of the mass of the bean to the mass of the pebble?

Where must a 20 g particle be placed so that the center of mass of this three-particle system is located at the origin? Options (-1,3)m (1,-3)m (-1,2)m (-1,7)m (-1,12)m (1,7)marrow_forwardIn the figure, a 20 kg bullet with velocity v passes through a 0.5 kg pendulum and exits with velocity v / 2. The pendulum is 2.5 m long and is suspended from a rope of negligible mass. What is the minimum velocity of the projectile for the pendulum to move in a complete vertical circle? (g = 10 m / s ^ 2)arrow_forward
- On a horizontal frictionless surface, a small block with a mass 0.200kg has a collision with a block of mass 0.400kg. Immediately after the collision, the 0.200kg block is moving at 12.0m/s in the direction 30° north of east and the 0.400kg is moving at 12.6m/s in the direction 53.1° south of east. a) what is the total kinetic energy of the two blocks after the collision (in joules) b) what is the the x-component of the total momentum of the two blocks after the collision? c) what is the the y-component of the total momentum of the two blocks after the collision?arrow_forwardA railroad car of mass m and speed v collides with and sticks to an identical railroad car that is initially at rest. After thecollision, is the kinetic energy of the system (a) 1>2, (b) 1>3, or (c) 1>4 of its initial kinetic energy?arrow_forwardA cannon of mass 6.79 x 103 kg is rigidly bolted to the earth so it can recoil only by a negligible amount. The cannon fires a 85.6-kg shell horizontally with an initial velocity of 508 m/s. Suppose the cannon is then unbolted from the earth, and no external force hinders its recoil. What would be the velocity of a shell fired from this loose cannon? (Hint: In both cases assume that the burning gunpowder imparts the same kinetic energy to the system.)arrow_forward
