a) A locomotive is travelling at 35 m/s up an incline of 0.006 radians when the engine cuts out. How far will the locomotive travel up the incline before coming to rest? Assume there are no frictional losses, no energy input from the engine, and take acceleration due to gravity to be 9.81 m/s². Give your answer in km. Round your answer to 4 significant figures. b) What is the speed (in m/s) of the locomotive after it has travelled a distance 5.83 km? Round your answer to 3 significant figures.
1 The quickest way to lose weight is to put yourself in free fall. In the thrill ride shown, the rider is spun in a circle at just the right speed so as to feel weightless at the top. This means that the rider's centripetal acceleration has the value g = 9.8 m/s? at the top. A) What is the period of rotation of the wheel? The wheel's radius is given in the picture. B) Draw a simple diagram of the rider's trajectory in space. At the top of the trajectory, draw and label vectors for the rider's velocity and acceleration. (picture is not to scale!) R = 15 meters INSTANT WEIGHT LOSS!
