- 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?A long track balanced like a seesaw supports a golf ball and a more massive billiard ball with a compressed spring between the two. When the spring is released, the balls move away from each other. Does the track tip clockwise, rip counterclockwise, or remain in balance as the balls roll outward? What principles do you use for your explanation?The 40-kg disk A with a radius of 0.4 m and the 25-kg crate B is attached to each other using the cable and pulley system shown in the figure. The coefficient of kinetic friction between the crate and the inclined plane, and between the disk and the inclined plane is 0.25. Neglecting the mass of pulleys and the mass of the cord and assuming that the cord does not slip over the pulleys. Determine the acceleration of the block B when the system is released, if the disk rolls without slipping. Also, calculate the tension in the cable and the angular acceleration of the disk at that instant.
- A child riding in a car holds a string attached to a floating, helium-filled balloon. As the car decelerates to a stop, the balloon tilts backwards. As the car makes a right-hand turn, the balloon tilts to the right. On the other hand, the child tends to be forced forward as the car decelerates and to the left as the car makes a right-hand turn. Explain these observed effects on the balloon and child. Hint: Review your Physics about centripetal accelereation. indicate the free bofy diagramYou 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…While driving his motorcycle at highway speed, a physics student notices that pulling back lightly on the right handlebar tips the cycle to the left and produces a left turn. Explain why this happens.

- Please answer vertically, not horizontally so that no steps are miscalculated for this problem. A unicorn is standing on a rotating platform so that it can be admired from every angle. The platform is 5 m in radius and rotates every 8 seconds (otherwise known as 1/8 of a rotation per second). What coefficient of friction must the unicorn's hooves have to keep him from slipping over the edge? This answer is not shown correctly on bartleby. Would he need a higher or lower coefficient of friction to stand closer to the center of the rotating platform? Explain.Please help: A 2.90 kg bucket is attached to a disk-shaped pulley of radius 0.131 m and mass 0.792 kg. If the bucket is allowed to fall, How far does the bucket drop in 1.20 s?A 4.00-kg stone is tied to a thin, light wire wrapped around the outer edge of the uniform 8.00-kg cylindrical pulley. The inner diameter of the pulley is 55.0 cm, while the outer diameter is 1.00 m. The system is released from rest, and there is no friction at the axle of the pulley. 1) Find the acceleration of the stone. Express your answer in meters per second squared. 2) Find the tension in the wire. Express your answer in newtons. 3) Find the angular acceleration of the pulley. Express your answer in radians per second squared.
