Q1. On a very muddy football field, a 110kg linebacker tackles an 85kg halfback. Immediately before the collision, linebacker is slipping with a velocity of 8.8m/s north and halfback is sliding with a velocity of 7.3m/s east.
Q2. A 67.3 ice skater moving to the right with the velocity of 2.52 throws a .151 snowball to the right with a velocity of 33.7 relative to the ground. What is velocity of the ice skater after throwing the snowball?
Q3. Locate the magnetic energy stored in the air gap between two very large magnet pole pieces, one North, one South, each with an area of 100 cm2. Imagine the 0.05 T magnetic field is uniform within the 2-cm gap.
