A roller-coaster car has a mass of 498 kg when fully loaded with passengers. The path of the coaster from its initial point shown in the figure to point B involves only up-and- down motion (as seen by the riders), with no motion to the left or right. Assume the roller-coaster tracks at points and Bare parts of vertical circles of radius r1 = 10.0 m and r2 = 15.0 m, respectively. (a) If the vehicle has a speed of...

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...
