... 14) You drop a bowling ball from the top of a tall building. One second later, you drop a pingpong ball from the same point. Neglecting air resistance, what can we say about the motion of the two balls? A) The bowling ball will hit the ground more than one second before the ping-pong ball. B) The bo ...

... 3. A boat moves through the water with two forces acting on it. One is a 2,000-N forward push by the water on the propeller, and the other is a 1,800-N resistive force due to the water around the bow. (a) What is the acceleration of the 1,000-kg boat? (b) If it starts from rest, how far will the bo ...

rotational inertia
... • To determine exactly where it lies, we have to suspend the object from some other point and draw a vertical line from that point of suspension. • Where the two lines intersect is the center of gravity. ...

Newton`s Wagon - Newton`s Laws
... Newton’s First Law of Motion also says that objects at rest will tend to stay at rest and objects in motion tend to stay in motion unless acted upon by an external force. You’ve seen this before – a soccer ball doesn’t move unless you kick it. But what happens if you kick it in outer space, far fr ...
