3. A ballistic pendulum consists of a sand box with a mass of 27 kg that is suspended from a cord 3 m long. A 0.5 kg shell is fired horizontally into the box and remains embedded in it. Because of the impact, the sand box swings through a maximum angle of 30° as shown in the figure. Determine the velocity with which the shell strikes the box. (10 pts) 30 3m. 0.5 kg 27 kg

A cannon is rigidly attached to a carriage, which can move along horizontal rails but is connected to a post by a large spring, initially unstretchcd and with force constant k = 2.00 104 N/m, as shown in Figure P8.60. The cannon fires a 200-kg projectile at a velocity of 125 m/s directed 45.0 above the horizontal. (a) Assuming that the mass of the cannon and its carriage is 5 000 kg, find the recoil speed of the cannon. (b) Determine the maximum extension of the spring. (c) Find the maximum force the spring exerts on the carriage. (d) Consider the system consisting of the cannon, carriage, and projectile. Is the momentum of this system conserved during the firing? Why or why not?
An bullet of mass m = 8.00 g is fired into a block of mass M = 250 g that is initially at rest at the edge of a table of height h = 1.00 m (Fig. P6.42). The bullet remains in the block, and after the impact the block lands d = 2.00 m from the bottom of the table. Determine the initial speed of the bullet. Figure P6.42
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? (a) 19 (b) 13 (c) 1 (d) 3(e) 9
A 3.00-g bullet is fired horizontally into a 10.0-kg block of wood suspended by a rope from the ceiling. The bullet becomes embedded in the wood, and, as the result, the block swings up in an arc, like a ballistic pendulum, rising 3.00 mm above its original position. Which of the following is the closest to the initial speed of the bullet? Group of answer choices a. 235 m/s b. 24.3 m/s c. 75.0 m/s d. 811 m/s e. Cannot be determined since the heat generated in the collision is unknown
(I) In a ballistic pendulum experiment, projectile 1 resultsin a maximum height h of the pendulum equal to 2.6 cm.A second projectile (of the same mass) causes the pendulumto swing twice as high h2=5.2 cm, The second projectilewas how many times faster than the first?
A cannon of mass 1 500 kg fires a 10-kg shell with a velocity of 280 m/s at an angle of 55 degrees above the horizontal. Find the recoil velocity of the cannon across the level ground Choose: A. 0.56 m/s B. 1.07 m/s C. 0.76 m/s D. 0.96 m/s
A 1.35-kg block of wood sits at the edge of a table, 0.782 m abovethe floor. A 0.0105-kg bullet moving horizontally with a speed of715 m>s embeds itself within the block. What horizontal distancedoes the block cover before hitting the ground?
A 0.420 kg block of wood hangs from the ceiling by a string and a 0.0750 kg wad of putty is thrown straight upward, striking the bottom of the block with a speed of 5.74 m/s. The wad of putty sticks to the block. How high does the putty-block system rise above the original position of the block?
A shell is shot with an initial velocity v→0 of 11 m/s, at an angle of θ0 = 53° with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass (see the figure). One fragment, whose speed immediately after the explosion is zero, falls vertically. How far from the gun does the other fragment land, assuming that the terrain is level and that air drag is negligible?

. The fisherman's mass is 79 kg, and the boat's is 126 kg. The fisherman and boat are initially at rest when the fisherman throws a package of mass m = 15 kg horizontally to the right with a speed of vi = 4.9 m/s. What is the velocity of the boat after the package is thrown? Neglect any resistance force from the water. (Give the magnitude in m/s, and select the correct direction from the options given.) What is the direction of the boat?
A bullet is fired horizontally into an initially stationary block of wood suspended by a string and remains embedded in the block. The bullet’s mass is m = 0.0065 kg, while that of the block is M = 0.92 kg. After the collision the block/bullet system swings and reaches a maximum height of h = 1.15 m above its initial height. Neglect air resistance.
