I don't see why I should use momentum because at the end of the sequence the bullet-block combination is motionless (vfinal = 0) and the angle is the angle max. And to konthelion: Why wouldn't it be what I wrote if the initial velocity of the bullet is what contains all the energy of the...

Homework Statement A bullet with a masse (m) is shot into a block of wood with a masse (M) at a velocity of (v). The bullet is lodged into the block of wood which is attached to a string of (l) length. After the impact where the velocity of the wood-bullet mass is equivalent to zero, the...

Yes, it's given. And sorry my attempt is a bit poor, I just need a bit of help starting off in the right direction. Thanks

Homework Statement An object (masse m) is placed on a slope with an angle a at a height of h above the ground. There is no friction on the inclined plane. The inclined plane leads to a horizontal plane 2 meters long that ends with a spring with a constant of k. There is friction on the...
