Today’s physics puzzler:
You’re holding a bowling ball, while sitting in a boat, which is floating in a swimming pool.When you drop the ball overboard, the water level in the pool will:1. rise a little.2. fall a little.3. stay the same.

1 of 3Jogger B runs along a circular track at constant speed from point 1 to point 2. Jogger A runs at constant speed along the straight line joining 1 and 2. Both joggers leave 1 simultaneously, and arrive at 2 simultaneously. A’s speed is:
1. greater than B’s.2. equal to B’s.3. less than B’s.4. incomparable to B’s without more information.

2 of 3Jogger B runs along a circular track at constant speed from point 1 to point 2. Jogger A runs at constant speed along the straight line joining 1 and 2. Both joggers leave 1 simultaneously, and arrive at 2 simultaneously. The magnitude of A’s average velocity is:
1. greater than that for B.2. equal to that for B.3. less than that for B.4. incomparable to that for B without more information.

3 of 3A bicyclist follows the bike path starting at point 1 heading east at first. The path eventually leads back around to point 1. If the path length is 5 miles, and the cyclist completes the trip in 30 min, then the magnitude of the cyclist’s average velocity would be:
