Answer #1

Total Energy at A= Total energy at B x 900 x (0) + (900x cox 10) = amb » 135000 = L x 900 Vo [VB = 17.32 m/s Total energy at

    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...
