Q1) Two identical pucks collide on an air hockey table. One puckwas originally at rest. If the incoming puck has a speed of 6.50m/s and scatters to an angle of 30.0º,what is the speed of thesecond puck after the collision?
(You may use the result that θ1−θ2=90º forelastic collisions of objects that have identical masses.)
Q2)A block of mass m = 3.0 kg, moving on a frictionless surfacewith a speed 2.9 m/s makes a perfectly elastic collision with ablock of mass M at rest. After the collision, the 3.0 kg blockrecoils with a speed of 0.8 m/s. In Fig. 1, the mass M (in kg) isclosest to:
