A cannon fires a cannonball. Identify the action-reaction pairs when the cannonball is in flight (after it is fired and is no longer in contact with the cannon). Assume air friction can be neglected.

Figure 9 on page 362 shows various motions of balls. the curved path followed by the yellow ball in b in picture b is result of a) inertia b) centripetal motion c) gravity and horizontal velocity d) linear motion

What is a subatomic particle with a negative charge and very little mass?

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?
