has an initial speed of 20 m/s, and puck 2 has an initial speed of 15 m/s.

Question:

has an initial speed of 20 m/s, and puck 2 has an initial speed of 15 m/s. They collide, and some glue on one of the pucks causes them to stick together.?

(a) If the two pucks form a ???system,??? is the momentum of this system along x or y conserved?

(b) Find the components along x and y of the initial velocities of both pucks.?

(d) Is this collision elastic or inelastic??

(e) Find the final velocity of the two pucks after the collision.?

(f) What fraction of the initial kinetic energy is lost in the collision?
