7) California Screamin' in Disney's California Adventure park is one of my favorite roller coasters. It begins with a "catapult launch" in which the train is propelled by "linear synchronous motors" from 0 to 25 m/s (-55 mph) along 66 m of horizontal track. The train itself has a mass of approximately 5000 kg, and holds 24 people of 75 kg each on average a) Determine the average propelling force (in Newtons, and then lbs) for a train with 24 people Assume the force is horizontal, along the track. Ignore friction.) Use WET (K b) Determine the time it takes (assuming constant force and acceleration). c) Determine the average power needed to launch the train, first in watts, then in h.p
