A 10.0 gram bullet traveling at 275 m/s strikes and embeds itself in a 3.490 kg block of wood held on a frictionless table by a spring having k= 50.0 kg/sec^2. Calculate the speed of the block immediately after the collision and the compression of the spring in meters.
Problem (1) (40 points) A pendulum consisting of a ball of mass m and a massless string of length L 5.00 m is released from an angle of a 69 88 shown in the figure and strikes a block of mass M 2m. The block slides a distance D before stopping under the action of a constant friction force with the frio- tion constant μ": 0.50. The ball rebounds to an angle of Hints: Take g= 10 m/?. sin 16"...
A projectile of mass m moves to the right with a speed vi
(Fig. P11.50a). The projectile strikes and sticks to the end of a
stationary rod of mass M, of length d, that is pivoted about a
frictionless axle through its center (Fig. P11.50b).
a) Find the angular speed of the system right after the
collision. (Use vi, m, M, and d as appropriate in your
equation.)
(b) Determine the fractional loss in mechanical energy due to
the collision....

1. Determine whether the statements below are true or false: a. [4 points) Two carts move in the same direction along a frictionless track, each acted upon by the same constant impulse. If Cart 1 has the twice the mass of Cart 2, then Cart 2 will have the greater change in linear momentum. b. [4 points) Any force component that causes a centripetal acceleration cannot change the translational kinetic energy of the object. c. [4 points) A...
Two particles approach each other with equal and opposite speed, v . The mass of one particle is m , and the mass of the other particle is n m , where n is just a unitless number. Snapshots of the system before, during, and after the elastic collision are shown. Elasic collision in three stages. Before the collision, a ball of mass m moves to right at speed v and a ball of mass n times m moves to...
