A roller-coaster car has a mass of 1450 kg when fully loaded with passengers. As the car passes over the top of a circular hill of radius 17 m, its speed is not changing
A bicycle is rolling down a circular hill whose radius is 9.00 meters. The angular displacement of the rider entering and leaving the radius which joins the hill to flat terrain is 0.960 rad. The radius of each wheel is 0.400 meters. What is the angle (in radians) through which each tire rotates?
The crest of the second hill is circular, with a radius of r = 35.0 m. Neglect friction and air resistance. What must be the height h of the first hill so that the skier just loses contact with the snow at the crest of the second hill?
