A 10kg sled slides down a frictionless icy hill at an angle of 25 degrees. Calculate the parallel component of the sled's weight. Calculate the acceleration of the sled.
Would b) require the force of gravity, or all forces of gravity (parallel, perpendicular, regular, etc)?

You are asked to design a rollercoaster. It will have ten attached cars, each of which will have a mass of 500 kg and carry six people with average mass of 70.0 kg. You want to design a vertical circular loop with a radius of 55.0 m. The centre of the circle would have a height of 71.0 m above the ground. Assume the track is frictionless. assume the rollercoaster is designed to operate at the minimum speed at the top of the loop.Calculate the speed of the cars when they are 40? below the horizontal.
