A battleship simultaneously fires two shells toward two identical enemy ships. One shell hits ship A, which is close by, and the other hits ship B, which is farther away. The two shells are fired at the same speed. Assume that air resistance is negligible and that the magnitude of the acceleration due to gravity is .
For two shells fired at the same speed which statement about the horizontal distance traveled is correct?
The shell fired at a larger angle with respect to the horizontal lands farther away.
The shell fired at an angle closest to 45 degrees lands farther away.
The shell fired at a smaller angle with respect to the horizontal lands farther away.
The lighter shell lands farther away.

A spaceship of length L moves with a speed 7c/12 with respect to the ground. A ball is thrown from the back of the ship to the front. The speed of the ball with respect to the ship is c/3. Apply the Lorentz transformations to find:
For high frequency sounds, the ear's principle method of localization is the difference in intensity sensed by the two ears. why can't the ear reliably use this method for low-frequency sounds? doesn't the head cast a "sound shadow" regardless of ..
