Mass=1kg(M), which is immobile and is standing on the equillibrium point,is attached on a spring with k=400N/m.We move the mass M to a point D which is d=0.2 m away from the equillibrium and then we set it free to move.At the moment t=0 the mass M passes from the equillibrium for the first time and it collides (headon collision) plastically with another mass m=3 Kg which is moving with u2 velocity.The new (M+m) body just after the collision has a velocity with the same direction of the velocity of mass M just before the collision and it immobilizes for a moment for the first time after its creation to a point E which is d1=0,25m away from D.
Find
1) the Energy of the oscillation of the body (M+m)
2)the u2.
3)the percentage of the kinetic energy of the wo masses beforethe collision,which turnd into heat because of the collision.
Hint:m1 is moving to the left,m2 is moving to the right.
