A car on a roller coaster starts at zero speed at an elevation above the ground of 20.8 m. It coasts down a slope, and then climbs a hill. The top of the hill is at an elevation of 14.77 m. What is the speed, in m/s, of the car at the top of the hill? Neglect any frictional effects; g=9.80 m/s2.
A projectile is shot from the surface of Earth by means of a very powerful cannon. If the projectile reaches a height of 30,614 m above Earth's surface, what was the speed of the projectile when it left the cannon? (G=6.67x10-11 m3 kg-1 s-1, mass of Earth is 5.97x1024 kg, and radius is 6.37x106 m)

A 4,500-kg roller coaster cart has a speed of 4.76 m/sm/s when it reaches its first peak at a 99.0 mm height from the ground level. After descending, it climbs up the second hill which is 84.2 mm above the ground level. How fast is the roller coaster cart at the top of the second hill? Assume there is no friction with the rails and no air resistance during the cart's motion.
