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.

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.

How did you done?

A satellite used in a cellular telephone network has a mass of 2010kg and is in a circular orbit at a height of 770km above the surface of the earthWhat is the gravitational force Fgrav on the satellite? Take the gravitational constant to be G = 6.67×10−1...
