Q:
1) A supersonic jet is fiying west at one-third of its maximum speed. The jet's top speed is
5,400 kilometers per hour. If the jet's velocity remains constant, how much time will it take
the jet to fiy 3,600 kilometers?
Q:
4) Sanjay shoots a hockey puck in the last 15 seconds of a hockey game. The puck is now
sliding toward the goal at 15 meters per second. If its velocity remains constant how much
time will it take the puck to slide 27 meters?
Q:
A) A maple tree seed is falling straight down at 92 centimeters per second. If its velocity
remains constant, how long will it take the seed to fall 230 centimeters?
b) Write your answer to the tenths place.
Q:
A square conducting wire, in a plane with an infinitely-long current-carrying wire, is oriented with one of its sides parallel
to the long wire. The square is equipped with an ideal battery (which doesn't contribute to the physical dimensions of the
square) and exhibits a fixed resistance. It is pulled at a constant speed directly away from the long wire, while remaining
in the same plane. The grid lines give an indication of how the dimensions of the square compares to the position of the
square relative to the wire at a single moment in time.

Pregunta 10
En un juego de billar una bola \( A \), de 160 g , que se mueve a una velocidad \( V_{A} \), choca
frontal y elásticamente con otro bola \( B \), de 165 g , que está en reposo, Si después del
choque se mueven en direcciones contrarias, la bola \( A \), a \( 1,8 \mathrm{~m} / \mathrm{s} \) y la bola \( B \), a \( 2 \mathrm{~m} / \mathrm{s} \). ¿A
qué velocidad se mueve la bola \( A \) antes del choque?
