The company is designing an electromagnetic propulsion system for a new roller coaster A model of a substructure of the device appears in the figure below ered in a uniform downward The rod is of length -1.00 m and mass-0600 kg. The red cames acert-200A in the direction shown and along the rails of length -200m without sipping. The entire system of directed magnetic field with magnitude 82.10 T The electromagnetic forca roll to the right in the figure when a full-scale device is produced, this rad its passengers ride. The electromagnetic force on the axe will provide the ma to the rails, causing the red to of wheels on which the car and at the beginning of the roler-coaster ride. Your supervisor wants to test the substructure in the figure in a flat outdoor ares on the grounds of the company. By projecting the rod from the rails in a horizontal direction from a height 130m, the projection spont can be determined from how far from the ends of the rails the rod Nits the ground. Your superior an you to determine the length of the subdoor are needed to test the device. (Determine the total horizontal distance, if the intalpostion of the red on the tracks to the al position of the rod where it lands on the ground) Need Help? 18.
