A 4 kg ball moving at 14 m/s in southwest. What is the A) x- (east-) component and B) y- (north-) component of the momentum vector of this ball? It collides with a stationary 6 kg ball. C) What is the magnitude of the momentum vector of this ball? After the collision, the 4 kg ball moves at 13.5 m/s, at an angle of 50 degrees from west to south. What is its C) x-component and D) y-component of the momentum vector for the 4 kg ball now? (round answers to 3 sig figs) Then, find the E) x-component and F) y-component of the velocity for the 6 kg ball. (round answers to 1 dp)

An electron starts from rest 15.0 cm from the center of a uniformly charged insulating sphere of radius 10.0 cm and total negative charge -3.00 μC. What is the maximum speed (in m/s) the electron can reach after releasing it? (Note: suppose a referen..
A floodlight with a mass of 46.00 kg is used to clarify the parking lot in front of a library. The floodlight is supported at the end of horizontal beam that is hinged to a vertical pole. A cable that makes an angle of 29 degrees with the beam is att..
An Airbus A310 is initially moving down the runway at 7.0 m/s preparing for takeoff. The pilot pulls on the throttle so that the engines give the plane a constant acceleration of 1.9m/s2. The plane then travels a distance of 1600 m down the runway be..
14 6C (mass = 14.003242 u) undergoes beta decay to 14 7N (mass = 14.003074 u). Write the complete decay formula for this process. Find the maximum kinetic energy of the emerging electrons.
Two negative point charges are separated by 11.0cm and feel a mutual repulsive force of 1.85?N . The charge of one is three times that of the other. How much charge does each have? in nanocoulumbs
Determine the resultant velocity of an airplane that normally flies at 200 k/h if it encounters a 50 km/m tailwind if it encounters a 50 km/h headwind
If you were to drop a ball, releasing it from rest, what information would be needed to predict how much time it would take for the ball to hit the floor? What assumptions must you make
The greatest height reported for a jump into an airbag is 99.4 m by stuntman Dan Koko. In 1948 he jumped from rest from the top of the Vegas World Hotel and Casino. He struck the airbag at a speed of 39 m/s (88 mi/h).
A point (x,y) in the plane is called a lattice point if both x and y are integers. Find the side length of the largest square that contains exactly three lattice points in its interior. Your answer should be given in exact form, and completely ju..
