1.Consider a roller coaster (m = 219.0 kg) at the lowest point on its track, where the radius of curvature is r = 20.0 m. If the velocity of the roller coaster is 16.0 m/s, calculate: (g=9.80 m/s2). Find the centripetal force.
2.Consider a roller coaster (m = 208.0 kg) at the lowest point on its track, where the radius of curvature is r = 24.0 m. If the velocity of the roller coaster is 23.0 m/s, calculate: (g=9.80 m/s2). Find the normal force.

The mass of a roller-coaster, including its passengers, is 500.0 kg. The radius r 2 of the highest track (point B) in the figure is 40 m. Find the speed of the roller-coaster when the passengers feel weightless at the the top of the track. Weightless is the condition when the contact force between the coaster and the track is zero, that is, the normal force is zero. Use g = 10 m/s. 20 m/s 10V3 m/s 10 m/s 10v5...

90 m (15 points) A roller coaster ride at an amusement park lifts a car of mass 700 kg to point A at a height of 90 m above the lowest point on the track, as shown above. The car starts from rest at point A. rolls with negligible friction down the incline and follows the track around a loop of radius 20 m. Point B. the highest point on the loop, is at a height of 50 m above...
