A roller coaster includes a long ramp that leads into a Loop-D-Loop. A carriage starts from rest at the top of the ramp and rolls downward (the system is frictionless) The value of gravitational acceleration is 4.8m/s, The mass of the carriage is 80kg, The initial height of the carriage is 5, and the radius of the Loop-D-Loop 10m 1. a) Draw a photo of the carriage at the top of the ramp, and another at the top of the Loop. b)Calculate the velocity of the carriage at the top of the Loop-D-Loop?
Suppose that humans have created a colony outside of our solar system on a planet called Wfirst21. Wfirst21 has a mass of 1.45×1025 kg and a day that lasts 24.1 h (which defines the rotational period of the planet). The colony is located on the planet's equator. The colonists set up a communications satellite which orbits Wfirst21. The satellite has a circular orbit that keeps it positioned directly above the colony. Calculate the radius ?r of the satellite's orbit in kilometers.
Artificial gravity is a must for any space station if humans are to live there for extended length of time. An effective way to create artificial gravity is using a rotating enclosed cylinder. Humans walk on the inside of the outer edge of the cylinder, which has a diameter of D=3450m that is large enough such that its curvature is not readily noticeable to the inhabitants. Once the space station is rotating at the necessary angular speed w to create an artificial gravity of 1g, how many minutes would it take the space station to make one revolution?
You have a summer internship at NASA and are working on plans for a new space station to be launched into orbit around the Earth. The design of the space station is shown. i It is to be constructed in the shape of a hollow ring of mass 52,000 kg. The structures other than the ring shown in the figure have negligible mass compared to the ring. Members of the crew will walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius r = 140 m. The thickness of the ring is very small compared to the radius, so we can model the ring as a hoop. At rest when constructed, the ring is to be set rotating about its axis so that the people standing inside on this deck experience an effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the rim of the ring. Your supervisor asks you to determine the following: (a) the time interval during which the rockets must be fired if each…

When the motor runs, the buckets will rise. i. Calculate the diameter of the rod so that the bricks can be raised at a constant speed of 3.5 km/h when the motor is running at 490 revolutions per minute? ii. If the bricks are to have an upward acceleration of 0.65 m/s2, calculate the angular acceleration of the rod.
