Question

             Problems 1.) From your experimental and calculated data, calculate theK.E. of the ball before impact and the K.E. of the pendulum andball combination just after impact. Was the K.E. conserved? Whatbecomes of the difference in K.E. 2.) A 5.0kg piece of putty traveling east at a speed f2m/s collides with a 3.0kg piece of putty traveling wast at a speedof 4m/s/ the two pieces stick together after collision.
