A block that has a mass M = 500g is hanging at rest on a light string. A projectile with a mass m = 15g moving horizontally with a velocity of 255m/s strikes M and sticks in it. The block and its projectile swing up. How high does the center of mass rise?
A. 1.4 m
B 3.2 m
C .33 m
D .83 m
E 2.8 m

A bullet of mass m = 40 g, moving horizontally with speed v, strikes a clay block of mass M=1.33 kg that is hanging on a light inextensible string of length L=0.767. The bullet becomes embedded in the block, which was originally at rest. What is the smallest value of vv which would cause the block-on-a-string to swing around and execute a complete vertical circle?

A 5g BB is shot into a 500g wooden block. The BB travels horizontally and the block rests on a horizontal surface. The block is initially at rest. The BB embeds in the block. No friction between the surface and the block. If the BB was traveling at 400 m/s just as it strikes the block, what is the velocity of the combined block/BB as it moves off.

1- A ball with mass M, moving horizontally at 2.8 m/s, collides elastically with a block with mass 3.6M that is initially hanging at rest from the ceiling on the end of a 58-cm wire. Find the maximum angle through which the block swings after it is hit, in degrees. 2- A 0.15 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.72 m/s.

A projectile of mass m is shot into a block of mass M. The block is initially at rest at the edge of a frictionless table. The table top is a height h above the floor. The projectile hits and sticks to the block. After impact the masses land a distance d from the edge of the table. Determine the expression for the initial speed of the projectile.

A bullet is shot at a block that is initially at rest that is hanging from a cord. The bullet has a mass of 20 grams and and an initial speed of 650 m/s. If the block has a mass of 5kg and the bullet inside the block after the collision, what is the maximum height the block can swing after the collision?

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
