    A bullet of mass 45 g hits a block of mass 3.66 kg with a speed v. After the collision, the bullet emerges at the other end of the block with a speed of 87 m/s, and the pendulum swings up over an angle of 38°.

    A bullet of mass m = 5.00 g is fired into a block of mass M = 500 g initially at rest at the edge of a frictionless table of height h = 1.20 m. The bullet remains in the block, and after impact the block lands a distance d = 0.80 m from the bottom of the table. Determine the initial speed of the bullet.

    A bullet of mass 10 g is fired horizontally into a block of wood of mass 2 kg and suspended like a ballistic pendulum. The bullet sticks in the block and the impact causes the block to swing so that its center of gravity rises 0.1 m. Find the velocity of the bullet just before the impact. Can someone also explain the steps to me? I am very confused on all of this. Thank you

    12. (20 points) A 5 gram bullet is fired at a wood block that is supported at rest on a smooth incline plane (no friction) at an angle of theta above the horizontal. The bullet is fired with a speed of 500 m/s, but then impacts and passes straight through the wood block, coming out the other side with a speed of 400 m/s. As a result of the collision, the wood block slides up the ramp 5 cm from...

    A bullet of mass m = 23 g is fired into a wooden block of mass M = 4.4 kg as shown in the figure below. The block is attached to a string of length 1.5 m. The bullet is embedded in the block, causing the block to then swing as shown in the figure. If the block reaches a maximum height of h = 0.25 m, what was the initial speed of the bullet? m/s Bullet

    A bullet of mass 8 g is fired into a 1.2 kg ballistic pendulum (a block of wood acting as the pendulum bob of a thin metal arm attached to a low friction pivot point) that is initially at rest. The bullet exits the block of wood with a speed of 180 m/s and the wooden block swings from its lowest point to a maximum height of 9.2 cm above that location. Determine the velocity of the bullet before it...
