Q. Old naval ships fired 15 cannon balls from a 200 cannon. It was very important to stop the recoil of the cannon, since otherwise the heavy cannon would go careening across the deck of the ship. In one design, a large spring with spring constant 2.0×10^4 was placed behind the cannon. The other end of the spring braced against a post that was firmly anchored to the ship's frame.
Suppose a ping-pong ball and a bowling ball are rolling toward you with the same momentum, and you exert the same average force in stopping each of them.
A cannonball shot with the initial velocity of 129 m/s at an angle of 36° follows a parabolic path and hits a balloon at the top of its trajectory. Neglect air resistance, how fast is the cannonball going as it hits the balloon.
A 2.30-? F capacitor is fully charged by being connected to a 6.0-V battery. The fully charged capacitor is then connected to a 0.250-H inductor.
Two people are holding up the ends of a 4.75-kg wooden board that is l = 2.00 m long. A m = 3.00-kg box sits on the board, 0.50 m from one end. What forces do the two people exert.
A thin copper rod 1 m long has a mass of 50 g. What is the minimum current in the rod that would allow it to levitate above the ground in a magnetic field of magnitude 0.100 T.
Portray how asynchronous simulation can be used to predict the motions of this system and outline the data structures that would be necessary to implement such a program.
