Oppgave3

A projectile of mass m speed um is shot into a block of mass M, which is attached to a spring of

length and spring constant k. The projectile becomes stuck in the block after the collision. What

will be the amplitude of the oscillation after the collision? Describe the energy in the system before

and after collision.3.1

i need in answer: when we talk about collision, the amount of conservation will be the same before

and after collision. And after collision, the projectile and the block will be one body together.

Therefore: mvm + MvM = vlemet (m + M) bruk kinetisk energien til legemet
