An engineer must design a curved exit ramp for a highway in such a way that a car, exiting at the posted speed limit of 13.41 m/s (30 mi/hr), does not depend on friction to round the curve without skidding. The radius of the curve is 153.0 m. At what angle with respect to the horizontal must the curve be banked (in degrees)?

Find the speed of a satellite in a circular orbit around the earth with a radius 4.31 times the mean radius of the earth; RE 6.37E+3km; ME 5.98E+24kg.

The small spherical planet called "Glob" has a mass of 6.80×1018 kg and a radius of 6.50×104 m. A 48.0 kg satellite is in a circular orbit around the planet Glob at a height of 1.20×105 m above the planet's surface. Calculate the speed of the satellite.

A satellite is in a circular orbit around the earth. The period of the satellite is 27.1 hr. Calculate the radius of the orbit of the satellite. Data: Mass of the earth = 5.98 e+24 kg. What is the speed of the satellite?
