A puck of mass $m_1 = 0.50$ kg is sliding in the $+x$-direction at 1.50 m/s across a frictionless floor when it collides with a heavier puck of mass $m_2 = 3.2$ kg that is initially stationary. After the collision the smaller puck is moving in the $-y$-direction at 0.80 m/s.
What is the velocity of the heavier puck after collision? $\vec{v} = \text{____} \hat{i} + \text{____} \hat{j}$
What is the speed of the heavier puck after collision?
What is $\theta$, the angle that the heavier puck's velocity makes with the $x$-axis after collision?
What was $\Delta K_{tot}$, the change in the combined kinetic energy of these two pucks, during the collision?
