a) What is the momentum of the bullet before it hit the block?

b) Determine the velocity of the bullet, u, before it hit the block.

c) If the bullet-block system oscillates continuously, what would be the values of T, f, and

w, if the length of the cord is 1.96 m?

**bobpursley**, Sunday, September 1, 2013 at 11:39amyou know the height it went, what PE does it have, At the bottom when starting, it had that KE. From that, determine the velocity of block/bullet at impact.

now use conservation of momentum at impact

(M+m)V= momentumbullet

and now determine velocity bullet

Momentumbullet=m*v

c. I am not certain what your w means, angular momentum, or angular freq.

for T, T=2PI sqrt(length/g)

f= 1/T
