  A projectile is launched with an initial velocity of 28 m/s [52 degrees above horizontal], if the projectile lands on a platform that is 8m above the height that it was launched from, solve for; a) the velocity of the projectile just before it hits the platform.   b) the displacement of the projectile if it sticks to the platform (stays exactly where it lands).

We want to use a single ls command, with appropriate options, in order to list extended information about the files in our current working directory that match the following patterns: One or more zeros: e.g., 0 or 000 or 00000 or 000000 One or more ones: e.g., 1 or 11 or 1111 or 111111 Exactly 4 ones followed by 4 zeroes: i.e., 11110000 but we do not want to match any file like 0110010 or 10100 that feature another alternance of binary digits.
