Unformatted text preview: -1 when at the highest point of the loop. Assume that friction forces may be neglected and gravity, g = 9.81 N kg-1 C w v stone Figure 1 @ Avril Slone 2008 2 of 2 i. Calculate, for the passenger when at the highest point: a. The centripetal acceleration. b. The force the seat exerts on the passenger. ii. The passenger now moves and descends to the bottom of the loop. Calculate : a. The change in potential energy of the passenger in moving from the top to the bottom of the loop. b. The speed of the passenger on leaving the loop. iii. Operators of the ride must ensure the safety of the passengers and so must ensure that the speed at which the passengers enter the loop is above a certain minimum value. Suggest a reason for this. 2. Solve the second order differential equation 9 4 2 2 = + + t dt dx dt x d Figure 2 12 ms-1 7.0 m Passenger enters loop Passenger leaves loop...
