In the figure, a 6.67 g bullet is fired into a 0.376 kg block attached to the end of a 0.320 m nonuniform rod of mass 0.407 kg. The block-rod-bullet system then rotates in the plane of the figure, about a fixed axis at A. The rotational inertia of the rod alone about A is 0.0986 kg·m2. Treat the block as a particle. (a) What then is the rotational inertia of the block-rod-bullet system about point A? (b) If the angular speed of the system about A just after impact is 3.15 rad/s, what is the bullet's speed just before impact?

A uniform thin rod of length 0.56 m and mass 3.2 kg can rotate in a horizontal plane about a vertical axis through its center. The rod is at rest when a 3.5 g bullet traveling in the rotation plane is fired into one end of the rod. As viewed from above, the bullet's path makes angle θ = 60° with the rod. If the bullet lodges in the rod and the angular velocity of the rod is 12.0 rad/s...

A 50 gram lead bullet is fired at 450 m/s to a 3 kg block of copper and penetrates the block. Assuming that the bullet does not leave the block, if the initial temperature of the bullet is 60°C and the block is originally at 30°C, a) Find the final temperature of the bullet-block system. (Assume that the system is isolated and there is no heat escaping the system) b) Is the dissipated energy (due to the collision) enough to...

A bullet with mass m(lowercase m) is fired into a block of wood with mass M(uppercase M), suspended like a pendulum, and makes a completely inelastic collision with it. After the impact of the bullet, the block swings up to a maximum height h. Given the values of h = 5.00 cm = 0.0500 m, m = 6.75 g = 0.00675 kg, and M = 2.50 kg, (a) What is the (initial) velocity v_x of the bullet in m/s? (b)...
