A knife is dropped from the top of a 13.0 m high mast on a ship moving at 1.74 m/s due south.
(a) Calculate the velocity of the knife relative to the ship when it hits the deck of the ship. ________m/s (down)
(b) Calculate the velocity of the knife relative to a stationary observer on shore. ________m/s _________° (below the horizontal to the south)
(a) Discuss how the answers give a consistent result for the position at which the knife hits the deck.
Show that the change in momentum over a time interval [tsub0, tsub1] is equal to the integral of F from tsub0 to tsub1; that is, show that p(tsub1) - p(tsub0) = the integral from tsub0 to tsub1 F(t)dt.
In a transformer, the voltage across the primary coil is 120 V rms, and the voltage across the secondary coil is 10 kV rms (i.e. 10 000V). What is the impedance of the secondary coil
