detailed solution

4. The NEUST Gabaldon Campus is situated at the foot of Mount Mingan, which is part of the Sierra Madre mountain range. Mount Mingan has an elevation of 1.901 x 103 meters.12 Convert this height to units of (a) miles and (b) centimeters. 5. A red dwarf star in the constellation Centaurus, Proxima Centauri, is the nearest star to our Sun. Its distance from the Earth is 4.2421 light-years. Because of its proximity, its angular diameter can be measured directly, from which it can be determined that its diameter is about one-seventh of the diameter of our Sun.13 a. What is the distance (in mi) of Proxima Centauri from the Earth. (A light-year is equal to the distance that light travels in a year which is 9.4608 x 1015 m.) b. What is its diameter in units of feet? (The diameter of the Sun is 1,392,684 km.) 6. A car moving at 30 m/s uniformly slows down to a speed of 10 m/s in a time of 6 seconds. Determine the acceleration of the car. 7. A bus initially with a speed of 25 m/s slows down with an acceleration of -3 m/s2. How far does it travel before coming to a complete stop
