Consider the earth following its nearly circular orbit (dashed curve) about the sun.(Figure 2) The earth has mass mearth=5.98×1024kg and the sun has mass msun=1.99×1030kg. They are separated, center to center, by r=93millionmiles=150millionkm.

physic
Consider a train that rounds a curve with a radius of 570m at a speed of 160 km/h (approximately 100 mi/h)Calculate the friction force needed on a train passenger of mass 75kg if the track is not banked and the train does not tilt.
