Question

A 2.00 kg puck moving to the right at a velocity of 6.0m/s at an angle of 45.0 degrees below the horizontal collides with a 1.0 kg puck traveling to the right at a velocity of 3.0 m/s at an angle of 45.0 degrees above the horizontal. After the collision, the 2.0 kg puck moves toward the right at a velocity of 4.5 m/s at an angle of 25.0 degrees below the horizontal. What is the velocity of the 1.0 kg puck immediately after the collision?

Answer #1

negative sign in direction indicates the angle is made below the
horizontal

A puck with a mass of 1.2 kg moves with a velocity of 5 m/s in
the x-direction. It collides with a 1.6 kg puck which is initally
stationary. After the collision, the second puck moves at a

axis.

B)What is the velocity of the first puck after the
collision?

positive x axis. (a) Determine the velocity of the 0.300-kg puck
after the collision. (b) Find the fraction of kinetic energy lost
in the collision.
