Q. An ocean liner leaves New York City and travels 54.0° north of east for 199 km. How far east and how far north has it gone? In other words, what are the magnitudes of the components of the ship's displacement vector in the following directions?
Q. A 23 gram bullet traveling 230 m/s penetrates a 2.0 kg block of wood and emerge clearly at 170 m/s. If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges?
What is mass of the block of ice
An airplane is flying with a velocity of 81.0 m/s at an angle of 24.0^circ above the horizontal. When the plane is a distance 108m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment.
The pilot of the spaceship measures the length of the moving ship as 30 meters. Establish its length as measured by a person on earth.
